Protons and neutrons make up the mass of atoms. Electrons, miniscule compared to the protons and neutrons, contribute very little to the overall mass of atoms.Atoms and Isotopes Atoms of the same element have the same number of protons. All copper atoms have 29 protons. All helium atoms ...
When trying to find the number of neutrons, protons or electrons that different chemical species have, the periodic table is your best friend. Take a look at how to use the periodic table as well as nuclear notation to find the number of subatomic particles associated with any chemical species...

How Nuclear Radiation Works describes protons, neutrons and electrons in some detail. For example, hydrogen atoms have one electron orbiting the nucleus. Helium atoms have two electrons orbiting the nucleus. Aluminum atoms have 13 electrons circling the nucleus. Each atom has a preferred number of ...
By compressing the nucleus of the iron atom, we add energy to its 26 protons and 30 neutrons. If we press hard enough, the protons and neutrons will burst apart into what they're made of: smaller particles called quarks. We'll then have a mess of quarks -- the type of quarks called...
How to find the number of protons in an isotope What is the mass number of an isotope? How to find isotopic mass What is the percent abundance formula? How can you calculate the number of neutrons (n) in an atom? What is the mass number of the isotope lithium-7?
Protons have a positive charge, neutrons have a neutral charge, and electrons have a negative charge. Note that the atoms themselves can carry a positive or a negative charge. How? By gaining or losing electrons. The flow of electrons between atoms is what we call electricity. Since our bodi...
The center of an atom, called the nucleus, is composed of protons and neutrons. Protons are positively charged; neutrons have no charge at all; and electrons are negatively charged. The proton-to-electron ratio is always one to one, so the atom has a neutral charge. For example, a ...
For a more detailed explanation of why nuclear reactions release energy, and how much they can release, see the article binding energy on Hyperphysics.Artwork: Atoms are made of protons (red), neutrons (blue), electrons (green), and energy binding them together (yellow). By splitting large ...
