Question

What electrically neutral atom will have an electron configuration of 1s2 2s2 2p4?

Answer 1

Answer:- oxygen.

Explanations:- The electronic configuration is given and we are asked to figure out the electrically neutral atom that will have the electron configuration,
`1s^22s^22p^4` .

The sum of electrons for this electron configuration is 8. If we look at the periodic table then 8 is the atomic number of oxygen.

So, the electrically neutral atom for the given electron configuration is oxygen.
