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.
Magnesium's atomic radius is smaller than Calcium's.
The smaller atomic radius of a magnesium atom compared to a sodium atom is primarily a result of the increased nuclear charge in magnesium due to the higher number of protons. This increased nuclear charge pulls the electrons closer to the nucleus, resulting in a smaller atomic radius for magnesium.
No, aluminum has a larger atomic radius than sodium. Aluminum has a greater number of protons in its nucleus compared to sodium, leading to a larger effective nuclear charge that pulls its electrons closer, resulting in a smaller atomic radius.
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
Bromine has a larger atomic radius than magnesium. Atomic radius generally increases as you move down a group on the periodic table, so bromine, being below magnesium, has a larger atomic radius.

Barium (137.327) is larger than aluminum (24.305)
Sulfur has a larger atomic radius than magnesium. This is because as you move down a group in the periodic table, atomic radius increases due to the addition of more electron shells. Magnesium is higher up in the periodic table than sulfur, so it has a smaller atomic radius.
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.
Bromine has a larger atomic radius than magnesium. Atomic radius generally increases as you move down a group on the periodic table, so bromine, being below magnesium, has a larger atomic radius.
Calcium has a larger atomic radius than magnesium and a smaller atomic radius than potassium. This trend is due to the increase in number of protons and electrons as you move across the period on the periodic table from magnesium to calcium to potassium.
Cesium will have a larger atomic radius than magnesium. This is because atomic radius tends to increase down a group in the periodic table, and cesium is located below magnesium in the periodic table.
Sodium (Na) has a larger atomic radius than aluminum (Al).
Sodium has a larger atomic radius than aluminum.
