Ionization Energy Energy it takes to remove an electron from an atom. Across L-R increasing because more protons means more pulling is needed as the shells get full. Down U-D decreasing because there are more shells that get in the way of the pull, so it is weaker.
Electron Affinity the change in energy when gaining an electron in gases. Across L-R energy when forced to gain an electron increases because the shells get full. Down U-D decreasing because the shells are in the way and decrease the pull of the atom.
Electronegativity An atom's ability to attract electrons to itself. the stronger subtracts the weaker one to get electronegativity. Little difference means same 2 gases(covalent). Big difference means 2 different M+NM (ionic). Higher than 1.7 is considered ionic
Atomic Size radius size of elements. Across L-R decreasing because more protons. Down U-D increasing because of more shells.
Octet Rule having the same electron configuration as a noble gas.
Diatomic Elements when 2 of the same element bonds together
Ionic Compound strong ionic bonds hold ions in lattice formation. extremely high melting point. solids
Covalent Compound polar molecules, strong intermolecular bonds, higher melting point than non-polar, water. non-polar molecules, weak intermolecular bonds, lower melting point than polar, gas
