Question

The total number of s electrons in vanadium is:
A.6
B.8
C.10
D.7

Answer 1

The electron is a subatomic particle with a negative one elementary electric charge. Electrons are the first generation of the lepton particle family, and because they have no known components or substructure, they are considered elementary particles.

Complete answer:
Electronic configuration of elements – The electron configuration is the distribution of electrons in atomic or molecular orbitals of an atom or molecule (or other physical structure) in atomic or molecular physics and quantum chemistry.
Each electron is described as travelling independently in an orbital in an average field created by all other orbitals in electronic setups. Configurations are described mathematically by Slater determinants or configuration state functions.
Vanadium - Vanadium is a chemical element with the atomic number 23 and the symbol V. It's a malleable transition metal that's hard and silvery-grey in color. The elemental metal is uncommon in nature, but when isolated artificially, the creation of an oxide layer (passivation) protects the free metal from further oxidation.
Electronic configuration of vanadium – $1{s^2}2{s^2}2{p^6}3{s^2}3{p^6}4{s^2}3{d^3}$ .
So the total number of electrons in s orbital is - $(2 + 2 + 2 + 2) = 8$ .
So, the final answer is option (B) i.e., 8 .

Note:
By assisting in the determination of an atom's valence electrons, electron configurations provide insight into the chemical behavior of elements. It also aids in the classification of elements into separate blocks (such as the s-block elements, the p-block elements, the d-block elements, and the f-block elements).
