∙ 13y agoIt is rubidium. 1st group 5th period hence 5s1 at the back. count the number of electrons it has in its ground state and it adds up to 37 which is the proton number of rubidium.
Using exponents, the configuration reads :
1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 5s1
or [Kr] 5s1

But there is a 2p6 orbital missing. Just 20 electrons accounted for.
So correct electron configuration of iron would be 1s2 2s2 2p6 3s2 3p6 3d6 4s2. All 26 electrons accounted for.

Arsenic
Group 2 (Alkaline Earth Metals) Beryllium: 1s2 2s2 Magnesium: 1s2 2s2 2p6 3s2 Calcium: 1s2 2s2 2p6 3s2 3p6 4s2 Strontium: 1s2 2s2 2p6 3s2 3p6 3d10 4s2 4p6 5s2 Barium: 1s2 2s2 2p6 3s2 3p6 3d10 4s2 4p6 5s2 4d10 5p6 6s2 Radium: 1s2 2s2 2p6 3s2 3p6 3d10 4s2 4f14 4d10 4p6 5s2 5d10 5p6 6s2 6s2 6p6 7s2
Arsenic's atomic number is 33. That means neutral arsenic has 33 protons and 33 electrons. Thus, its electron configuration is 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p3.
1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p3.
