Question

An element has two electrons in it's M-shell. Identify the element.​

Answer 1

Answer:

The element is Magnesium.

The distribution of electrons is

k shell=2 electrons

l shell=8 electrons

M shell=2 Electrons

So the atomic number be 12

Then the element is Magnesium

$\huge\bold\purple{Answer:-}$

⏩ Since two electrons are present in the M-shell, the K-shell and L-shell of the element are completely filled. Electronic configuration of the element is 2(K), 8(L), 2(M). Hence, the total number of electrons in the neutral atom is 2 + 8 + 2= 12 or atomic number of the respective element is 12.

Thus, the element is identified as magnesium (Mg).
