It is 1s2 2s2 2p6 3s2 3p6
Because then it would be zinc!Calcium has the electron configuration [Ar] 4s2Zinc has the electron configuration [Ar] 3d10 4s2
Neon

No. Oxygen is an electron receptor (oxidizer) whereas Ca is a doner.
The element calcium, or Ca, is located in group 2, period 4 of the periodic table. Therefore, its electron configuration is 1s2 2s2 2p6 3s2 3p6 4s2. This can also be written as [Ar] 4s2, because the beginning of that electron configuration is the same as argon's. The 42 you mentioned in your question is referring to a specific isotope of calcium and has nothing to with the electron configuration.
The electron configuration of calcium is [Ar]4s2.
The electron configuration of calcium is [Ar]4s2.

Neutral calcium's electron configuration is 1s2 2s2 2p6 3s2 3p6 4s2. Ca2+ is the ion of calcium, which means that it has 2 less electrons than neutral calcium. Therefore, its electron configuration is 1s2 2s2 2p6 3s2 3p6.

if you mean how many are in it then there are 20
