Which element is predicted to have the smallest atomic radius? Justify the answer
Atomic size increase down the group and decreases across a period. In first period in periodic table we have Hydrogen and Helium. In hydrogen only one electron is present in outermost shell and in helium 2 electron are present, hence on going from left to right in periodic table the nuclear charge increases hence the attraction between electron and nucleus increases so the atomic radii decreases.

Arrange these elements according to atomic radius. Largest radius Smallest radius Answer Bank Se Te Po S Rank the elements by effective nuclear charge, Zeff, for a valence electron. Highest Zeff Lowest Zeff Answer Bank Ba Pb Rn Bi Po
Electron radii problem. I thought that P(-3) would have the
smallest radius because it is the same as MG, but the answer key
says CA 2+ is the smallest. Can anyone explain this?
thanks.

Why does Ca have a bigger atomic radius than Na? The periodic trend for atomic radius says that the lower and more to the left an element is, the greater it's atomic radius. In our case, Na is more to the left, but the Ca is lower down. How do we reconcile this?
The element with the largest atomic radius is B Li OF Na
