Electrons, protons?
1 c (Cl in the 3rd row, 2 rows filled, next to the last in the 3rd)


2 b (Kr, last in the 4th row)


3 a (electronegativity is based on sharing of electrons, covalent bond is sharing, ionic bond is based on net charges)


4 c (electron shells have different energy levels, protons and neutrons are all in the nucleus)
