: Elements in the same column have similar chemical "personalities" because they have the same number of outer-shell electrons.
: Neutral particles in the nucleus; they add mass but don't change the element's identity. Variations in neutron counts create isotopes .
: A "theft" where a metal gives an electron to a non-metal, creating charged ions that stick together like magnets.
