Front

As you move down a GROUP on the periodic table, why does the atomic radius get bigger?

Back

The atoms have more energy levels for the electrons.

Front

As you move across a period on the periodic table, why does the atomic radius tend to get smaller? Options: 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.

Back

The atoms have more protons, pulling the electrons closer.
