Question

which of the following correctly represent the electronic distribution in MG atom?

a) 3,8,1
b) 2,8,2
c) 1,8,3
d) 8,2,2​

Answer 1

Answer:

b is the correct answer

Answer 2

Explanation:

the electron configuration is the distribution of electrons of an atom or molecule (or other physical structure) in atomic or molecular orbitals. ... This is also useful for describing the chemical bonds that hold atoms together.

In this case we are asked to find the electronic configuration of magnesium atoms so I will directly tell you the correct option that is -

Atomic number and the number of electrons in magnesium atom is 12. So, electronic configuration is 2, 8, 2 (because 12=2 + 8 + 2).
