Question

What is the atomic number of element with valence shell configuration of 6s²6p⁴ ?

How to find out the answer of this question?

Answer 1

You can write down the electronic configuration and count the number of electrons that will be equal to the no of protons in the atom.

The number of protons = atomic number of the element.
1 s2 2s2 2p6 3s2 3p6 3d10 4s2 4p6 4d10 5s2 5p6 4f14 5d10 6s2 6p4

Atomic number = 84
