Question

Element that has the same electron configuration of Chromium when it forms a +2 charge?

Answer 1

Titanium.

Step-by-step explanation:

Hello,

In this case, since chromium has 24 electrons (atomic number) in order to represent the electron configuration of Cr⁺² which means that it has lost two electrons in order to get positively charged, we must perform an electron configuration until 22 (24-2) as follows:

`Cr^(+2):1s^2,2s^2,2p^6,3s^3,3p^6,4s^2,3d^2`

In such a way, adding the electrons per sublevel and shell we count 22, which matches with the number of electrons of titanium and therefore with its very same electron configuration.

Best regards.
