Each element is defined by the number of protons found in each of its atoms. No matter how many electrons or neutrons an atom has, the element is defined by its number of protons. In fact, it's actually possible to have an atom consisting of only a proton (ionized hydrogen). The peri...

Ions are formed when an atom either loses or gains electrons. The number in thesuperscriptwill tell you the magnitude of this change. Say you have Cl-. How many electron, protons and neutrons does this ion have? The process for finding these values is very similar to what was done above...
Protons, neutrons, and the electrons surrounding them are long-lived particles present in all ordinary, naturally occurring atoms. Other subatomic particles may be found in association with these three types of particles. They can be created only with the addition of enormous amounts of energy, ...
A neutral atom has an atomic number of 12 and an atomic mass of 25. How many protons are in it? How many protons, neutrons, and electrons are present in an atom of copper whose atomic number is 29 and whose mass number is 64?
