As you move across a period on the periodic table the atomic radius tend to get smaller because, ______________.

• the atoms have more mass making them heavier.

• more neutrons, making the nucleus bigger.

• the atoms have more protons, pulling the electrons closer.

• the atoms have less energy levels for the electrons to occupy.
