What is an Ion?

This chemistry video tutorial explains what exactly is an ion. An ion is a particle with unequal numbers of electrons and protons. Atoms have equal numbers of protons and electrons and are therefore electrically neutral. Ions with more protons than electrons are positively charged and are called cations. Negatively charged ions are called anions and more electrons than protons. This video contains plenty of examples and practice problems that test your knowledge on ions.
