Electronic configuration of
Li= 2,1.
Be= 2,2.
Na=2,8,1.
Mg=2,8,2.

More shells means bigger size so Na and Mg is bigger atom than Li and Be.Lower valence
Electron means bigger size so Na is biggest of them four.
Atomic size increases when we go down the group and decreases when we go from left to right in a period.
Hope it helps.
