Neutral calcium has 20 protons and 20 electrons. The first 20 atomic orbitals are filled as 1s2 2s2 2p6 3s2 3p6 4s2. The shorthand for this is [Ar] 4s2 since argon's configuration is 1s2 2s2 2p6 3s2 3p6.
[Ar] 4s2 i think
1s22s22p63s23p64s2
[Ar] 4s2
Sodium
Iron
The shorthand electron configuration of magnesium is [Ne]3s2.
The electron configuration of calcium is [Ar]4s2.
[Ar]3d34s2 is the shorthand electron configuration for Vanadium (V).
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.
The 3s.
2, 8 is the electron configuration
The shorthand electron configuration of magnesium is [Ne]3s2.
You don't. Calcium is not an electron, calcium is a element
there is no shorthand configuration for helium. its electron configuration is 1s2
It is [Ne] 3S2.
[Kr] 5s2
[Ar]4s23d104p2
The shorthand electron configuration of aluminum is: [Ne] 3s2 3p1
The electron configuration of calcium is [Ar]4s2.
It is [Ar] 3d1 4s2
The electron configuration of zirconium is: [Kr]5s24d2
2.3!<-----wrong shorthand electron configuration for Boron (B on the periodic table) is [He] 2s2 2p1 because Shorthand means building on the last noble gas element. So put the closest Noble gas element before this one and then the new addition.
