Define electronegativity
the energy required to remove an electron from an atom increases across a period, decreases down a group
the ability of an atom to attract electrons towards itself increases across a period, decreases down a group
the size of an atom (radius of the electron cloud) decreases across a period, increases down a group
define ionization energy
the energy required to add an electron to an atom increases across a period, decreases down a group
the energy required to remove an electron from an atom increases across a period, decreases down a group
