Periodic Trends

Front

As you move down a group, atomic radius increases because - Options: you add more and more neutrons, you add more and more protons, you add more and more shells (energy levels), you add more atomic mass

Back

you add more and more shells (energy levels)

Front

Atom with the largest atomic radius in Period 4

Back

K

Front

Why does Cesium (Cs) have the lowest ionization energy in Group 1?

Back

Its 1 valence electron is very far from the nucleus, so little energy is needed to remove it.

Front

Of the halogens, which has the smallest radius? Options: F, Br, He, At

Back
