Which element does the electron configuration 1s2 2s2 2p2 represent
b
c
n
k

The given configuration represents carbon atom.

Explanation:

Electronic configuration tells us about the number of electrons that are present in an atom. It also determines the atomic number of an element.

For the given electronic configuration =

Total number of electrons = 2 + 2 + 2 = 6

The element which has atomic number '6' is carbon atom.

Hence,  the given configuration represents carbon atom.
