Determine the number of protons and electrons in an atom. Define atomic mass unit amu. Dalton's Atomic Theory explained a lot about matter, chemicals, and chemical reactions. Nevertheless, it was not entirely accurate because, contrary to what Dalton believed, atoms can, in fact, be broken apart into smaller subunits or subatomic particles. We have been talking about the electron in great detail, but there are two other particles of interest to us protons and neutrons. We already learned that J. J. Thomson discovered a negatively charged particle, called the electron. Rutherford proposed that these electrons orbit a positive nucleus. In subsequent experiments, he found that there is a smaller positively charged particle in the nucleus, called a proton. There is also a third subatomic particle, known as a neutron. Electrons Electrons are one of three main types of particles that make up atoms. Electrons are extremely small. The mass of an electron is only about \\textstyle\frac1{2000}\ the mass of a proton or neutron, so electrons contribute virtually nothing to the total mass of an atom. Electrons have an electric charge of 1–, which is equal but opposite to the charge of a proton, which is 1+. All atoms have the same number of electrons as protons, so the positive and negative charges "cancel out", making atoms electrically neutral. While protons and neutrons are located inside the nucleus at the center of the atom, electrons are located outside the nucleus in what is often called the electron cloud. Figure \\PageIndex{1}\ Electrons are much smaller than protons or neutrons. If an electron was the mass of a penny, a proton or a neutron would have the mass of a large bowling ball! Protons A proton is another one of three main particles that make up the atom. Protons are found in the nucleus of the atom – the tiny, extremely dense region at the center of the atom. Protons have a positive electrical charge of one 1+ and a mass of about 1 atomic mass unit 1 amu. Together with neutrons, they make up virtually all of the mass of an atom. ⚖️ Atomic Mass Units An atomic mass unit amu is defined as one-twelfth of the mass of a carbon-12 atom, which is about × 10−27 kg. Atomic mass units amu are useful, since the mass of a proton and the mass of a neutron are almost equal to 1 amu in this unit system. Neutrons The last of the three main particles that make up the atom is the neutron. Atoms of all elements except for most atoms of hydrogen have neutrons in their nucleus. Unlike protons and electrons, which are electrically charged, neutrons have no charge – they are electrically neutral. That's why the neutrons in the table below are labeled \n^0\. The zero stands for "zero charge". A neutron is slightly more massive than a proton see below and has about the same diameter. Neutrons are found in all atoms except for most atoms of hydrogen and may be found bound together with other neutrons and protons in the atomic nucleus. Since protons and neutrons are so much more massive than electrons, almost all of the mass of an atom comes from the nucleus, which contains all of the neutrons and protons. Table \\PageIndex{1}\ provides a summary of the properties of the three main types of subatomic particles. Table \\PageIndex{1}\ Properties of Subatomic Particles Particle Symbol Mass kg Mass amu Relative Charge Location proton p+ × 10−27 ≈ 1 1+ inside the nucleus electron e− × 10−31 ≈ 0 1− outside the nucleus neutron n0 × 10−27 ≈ 1 0 inside the nucleus Summary Electrons are a type of subatomic particle with a negative charge. Protons are a type of subatomic particle with a positive charge. Protons are bound together in an atom's nucleus as a result of the strong nuclear force. Neutrons are a type of subatomic particle with no charge they are neutral. Like protons, neutrons are bound into the atom's nucleus as a result of the strong nuclear force. Protons and neutrons have approximately the same mass, but they are both much more massive than electrons approximately 2,000 times as massive as an electron. The positive charge on a proton is equal in magnitude to the negative charge on an electron. As a result, a neutral atom must have an equal number of protons and electrons.

Electrons Electrons are one of three main types of particles that make up atoms. Unlike protons and neutrons, which consist of smaller, simpler particles, electrons are fundamental particles that do not consist of smaller particles. They are a type of fundamental particle called leptons. All leptons have an electric charge of \-1\ or \0\. Electrons are extremely small. The mass of an electron is only about 1/2000 the mass of a proton or neutron, so electrons contribute virtually nothing to the total mass of an atom. Electrons have an electric charge of \-1\, which is equal but opposite to the charge of a proton, which is \+1\. All atoms have the same number of electrons as protons, so the positive and negative charges "cancel out", making atoms electrically neutral. Unlike protons and neutrons, which are located inside the nucleus at the center of the atom, electrons are found outside the nucleus. Because opposite electric charges attract one another, negative electrons are attracted to the positive nucleus. This force of attraction keeps electrons constantly moving through the otherwise empty space around the nucleus. The figure below is a common way to represent the structure of an atom. It shows the electron as a particle orbiting the nucleus, similar to the way that planets orbit the sun. However, this is an incorrect perspective, as quantum mechanics demonstrates that electrons are more complicated. Figure \\PageIndex{1}\ Electrons are much smaller than protons or neutrons. If an electron was the mass of a penny, a proton or a neutron would have the mass of a large bowling ball! Protons A proton is one of three main particles that make up the atom. Protons are found in the nucleus of the atom. This is a tiny, dense region at the center of the atom. Protons have a positive electrical charge of one \\left +1 \right\ and a mass of 1 atomic mass unit \\left \text{amu} \right\, which is about \ \times 10^{-27}\ kilograms. Together with neutrons, they make up virtually all of the mass of an atom. Neutrons Atoms of all elements—except for most atoms of hydrogen—have neutrons in their nucleus. Unlike protons and electrons, which are electrically charged, neutrons have no charge—they are electrically neutral. That's why the neutrons in the diagram above are labeled \n^0\. The zero stands for "zero charge". The mass of a neutron is slightly greater than the mass of a proton, which is 1 atomic mass unit \\left \text{amu} \right\. An atomic mass unit equals about \ \times 10^{-27}\ kilograms. A neutron also has about the same diameter as a proton, or \ \times 10^{-15}\ meters. As you might have already guessed from its name, the neutron is neutral. In other words, it has no charge whatsoever and is therefore neither attracted to nor repelled from other objects. Neutrons are in every atom with one exception, and they are bound together with other neutrons and protons in the atomic nucleus. Before we move on, we must discuss how the different types of subatomic particles interact with each other. When it comes to neutrons, the answer is obvious. Since neutrons are neither attracted to nor repelled from objects, they don't really interact with protons or electrons beyond being bound into the nucleus with the protons. Even though electrons, protons, and neutrons are all types of subatomic particles, they are not all the same size. When you compare the masses of electrons, protons, and neutrons, what you find is that electrons have an extremely small mass, compared to either protons or neutrons. On the other hand, the masses of protons and neutrons are fairly similar, although technically, the mass of a neutron is slightly larger than the mass of a proton. Because protons and neutrons are so much more massive than electrons, almost all of the mass of any atom comes from the nucleus, which contains all of the neutrons and protons. Table \\PageIndex{1}\ Properties of Subatomic Particles Particle Symbol Mass amu Relative Mass proton = 1 Relative Charge Location proton p+ 1 1 +1 inside the nucleus electron e− × 10−4 −1 outside the nucleus neutron n0 1 1 0 inside the nucleus Table \\PageIndex{1}\ gives the properties and locations of electrons, protons, and neutrons. The third column shows the masses of the three subatomic particles in "atomic mass units." An atomic mass unit \\text{amu}\ is defined as one-twelfth of the mass of a carbon-12 atom. Atomic mass units \\text{amu}\ are useful, because, as you can see, the mass of a proton and the mass of a neutron are almost exactly \1\ in this unit system. Negative and positive charges of equal magnitude cancel each other out. This means that the negative charge on an electron perfectly balances the positive charge on the proton. In other words, a neutral atom must have exactly one electron for every proton. If a neutral atom has 1 proton, it must have 1 electron. If a neutral atom has 2 protons, it must have 2 electrons. If a neutral atom has 10 protons, it must have 10 electrons. You get the idea. In order to be neutral, an atom must have the same number of electrons and protons. Summary Electrons are a type of subatomic particle with a negative charge. Protons are a type of subatomic particle with a positive charge. Protons are bound together in an atom's nucleus as a result of the strong nuclear force. Neutrons are a type of subatomic particle with no charge they are neutral. Like protons, neutrons are bound into the atom's nucleus as a result of the strong nuclear force. Protons and neutrons have approximately the same mass, but they are both much more massive than electrons approximately 2,000 times as massive as an electron. The positive charge on a proton is equal in magnitude to the negative charge on an electron. As a result, a neutral atom must have an equal number of protons and electrons.
