Question

(1) What is the element with an electron configuration of
`1 s^2 2 s^2 2 p^6 3 s^2 3 p^6 4 s^2 3 d^3 ?`

Answer 1

Vanadium

Step-by-step explanation:

When an atom gains electrons, they fill different orbitals sets according to a specific order. You can follow the periodic table in increasing order. This electron ends with
`3d^3` so you just look at the 3rd element in the d-block. This is vanadium.
