Induim because as you go across a group and down a period (or across a period and down a group, I forget which is correct) the atomic radius gets larger.
Titanium (140 pm) has a larger covalent atomic radius than aluminium (125 pm).

Magnesium's atomic radius is smaller than Calcium's.
a larger nuclear charge
Bromide.
Sodium has a larger atomic radius than aluminum.
yes
Magnesium's atomic radius is smaller than Calcium's.
a larger nuclear charge
Magnesium isn't smaller than chlorine, it's larger. The atomic radius for magnesium is 145 pm and the atomic radius for chlorine is 79 pm. Both magnesium and chlorine are in the third period of the periodic table. The trend for atomic radius is that the elements generally get smaller as you move from left to right across the table in the same period.
Caesium atom has a larger atomic radius.
Bromide.
Sodium has a larger atomic radius than aluminum.
yes
What has a larger radii, a sulfur atom or sulfied ion and why
Smaller
Strontium
Atoms do not have a radius. A helium atom has a nucleus composed of at least two protons and maybe one or two neutrons. A magnesium atom nucleus (and every other atom on the periodic table other than hydrogen) is BIGGER than a helium nucleus. So if you look at it that way...magnesium is larger than helium
Protons have a larger mass, but it is unclear which (if either) have a larger radius. The electron does not seem to have ANY measurable radius.
