For a neutralatom, the number of electrons is the same as the number of protons. Often, the number of protons and electrons is not the same, so the atom carries a net positive or negative charge. You can determine the number of electrons in anionif you know its charge. A cation carrie...

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...
neutrons are found in the nucleus of the atom, while the electrons are outside the nucleus. The atomic number is the number of protons, while the mass number is the number of protons and neutrons. If an element is not charged, the number of electrons will equal the number of protons. ...
