Question

which element does the electron configuration 1s²2s²2p² represent?
o b
o c
o n
o k

Explanation:

Step1: Calculate total electrons

The superscripts represent the number of electrons in each orbital. So $2 + 2+ 2=6$ electrons.

Step2: Determine element by electron number

The atomic number is equal to the number of electrons in a neutral atom. Carbon (C) has an atomic number of 6.

Answer:

B. C
