Calcium is not a noble gas but an alkaline earth metal.
No. Radon is a noble gas.
The noble gas core notation for Calcium is [Ar]4s2. This notation represents the electron configuration of Calcium by using the nearest noble gas (Argon) as a reference.
It is supposed that ununquadium is a noble gas.
argon (atomic number 18) is the closest to calcium (atomic number 20)
Yes it is. Argon (atomic number 18) is the noble gas that is nearest to calcium (atomic number 20)
Noble gas family, of course!
Xenon belongs to the noble gas family on the periodic table and is part of the rare gases group.
[Ar] 4s2
Calcium will lose two electrons to gain the noble gas configuration of Argon.
The calcium ion formed when it achieves a noble-gas electron configuration is Ca2+, as it loses two electrons to have the same electron configuration as argon, a noble gas.
No. It is however highly unreactive, similar to noble gases (except under extreme conditions)
A calcium atom must lose 2 electrons to achieve a noble gas structure, as it will then have the same electron configuration as argon, a noble gas. This loss of electrons allows the calcium atom to have a full outermost electron shell, giving it greater stability.
