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

How does Magnesium's atomic radius compare to aluminum?
Magnesium's atomic radius is smaller than Calcium's.
How does calcium atomic radius compare to magnesiums radius and potassiums 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.
What is smaller than the atomic radius of Oxygen?
The atomic radius of oxygen is about 60 picometers. Therefore, atoms of elements such as hydrogen (25 picometers) and helium (31 picometers) have smaller atomic radii than oxygen.
Does an aluminum ion have a larger or smaller radius than magnesium?
An aluminum ion has a smaller radius than a magnesium ion because aluminum loses an additional electron compared to magnesium, resulting in increased nuclear charge and greater attraction to the remaining electrons.
How does calcium's atomic radius compared to magnesium radius and potassium radius?
The atomic radius of calcium is larger than magnesium but smaller than potassium. This trend is consistent with the periodic trend across Group 2 elements where atomic radius increases down the group due to additional electron shells. Additionally, going across a period from left to right, atomic radius decreases due to increasing nuclear charge pulling electrons closer.
How does Magnesium's atomic radius compare to aluminum?
Magnesium's atomic radius is smaller than Calcium's.
Why is Mg smaller than Cl?
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.
How does calcium atomic radius compare to magnesiums radius and potassiums 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.
What is smaller than the atomic radius of Oxygen?
The atomic radius of oxygen is about 60 picometers. Therefore, atoms of elements such as hydrogen (25 picometers) and helium (31 picometers) have smaller atomic radii than oxygen.
Does an aluminum ion have a larger or smaller radius than magnesium?
An aluminum ion has a smaller radius than a magnesium ion because aluminum loses an additional electron compared to magnesium, resulting in increased nuclear charge and greater attraction to the remaining electrons.
Which element has a larger radius magnesium or sulfur?
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.
What element has a smaller ionic radius than magnesium?
Examples are: Be, Al, Ti, V, Mn, Co, Ni etc.
Which bone is smaller the unla or the radius?
The radius is smaller than the ulna
How does calcium's atomic radius compared to magnesium radius and potassium radius?
The atomic radius of calcium is larger than magnesium but smaller than potassium. This trend is consistent with the periodic trend across Group 2 elements where atomic radius increases down the group due to additional electron shells. Additionally, going across a period from left to right, atomic radius decreases due to increasing nuclear charge pulling electrons closer.
Does an atom of fluorine have larger or smaller radius than an atom of iodine?
Smaller
What element has a larger atomic radius Magnesium or Bromide?
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.
Element M reacts with chlorine to for a compound MCl2 Element M is more reactive than magnesium and has a smaller radius than barium the element is?
Element M can be a choice of 4 elements, Beryllium, Magnesium, Calcium, or Strontium. The element must have an oxidation of +2, which means group 2 elements. The atomic radius of a barium atom is 222pm. Radium has a larger atomic radius that Barium, so that is eliminated, and Barium is the same as Barium so that is also eliminated.
