Periodic trends review

Front

As you move down a group, the 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

The atom with the largest atomic radius in Group 18 (the noble gases) is: Ar, He, Kr, Rn

Back

Rn

Front

As you move across the periodic table from left to right, what happens to the atomic radius and why?

Back

The atomic radius decreases because the number of protons increases, so attraction to electrons increases.

Front

Which atom has the largest atomic radius in Period 4 (row 4)?

Back

K

Front

Why does Francium (Fr) have the lowest ionization energy in Group 1?

Back

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

Front

Element with the smallest ionization energy in Period 6: Rn, Cs, Os, Tm

Back

Cs
