More on Atoms

Most atoms have the same number of protons and electrons and so have a neutral charge overall.

If an atom has more protons than electrons, it has more positive charge than negative charge, so the atom is positively charged.

If an atom has more electrons than protons, it has more negative charge than positive charge, so the atom is negatively charged.
