Question

Which of the following electronic configurations match correctly with its respective element?

• A. ${}_{16}S$ (2,10,4)
• B. ${}_{13}Al$ (2,6,5)
• C. ${}_{6}C$ (2,4)
• D. ${}_{5}B$ (2,2,1)

Answer 1

The correct option is C ${}_{6}C$ (2,4)

Electronic configuration of sulphur, aluminium, carbon and boron are given below:
Sulphur (Z = 16) $\to$ S (2,8,6)
Aluminium (Z = 13) $\to$ Al (2,8,3)
Carbon (Z = 6) $\to$ C (2,4)
Boron (Z = 5) $\to$ B (2,3)
