Question

what element has the configuration 1s²2s²2p²

Explanation:

Step1: Calculate the total number of electrons

The sum of the exponents in the electron configuration gives the total number of electrons. So, \(2 + 2+2=6\) electrons.

Step2: Relate the number of electrons to the atomic number

In a neutral atom, the number of electrons is equal to the atomic number. An element with atomic number \(6\) is carbon (\(C\)).

Answer:

Carbon (\(C\))
