Explanation:

Electron configuration is the distribution of electrons of an atom or molecule in atomic or molecular orbitals.

Note that: C is the symbol for carbon, P is the symbol for phosphorus, V is the symbol for vanadium, Sb is the symbol for antimony, and Sm is the symbol for Samarium.

s - orbital accepts maximum of 2 electrons

p - orbital accepts maximum of 6 electrons

d - orbital accepts maximum of 10 electrons

f - orbital accepts maximum of 14 electrons
