Question

The electronic configuration of element M is 2,8,4 in modern periodic the element placed in which group?​

Answer 1

The electronic configuration of element M is 2,8,4 .

The element is Silicon.

It is in group 14 of modern periodic table.

Answer 2

Period : 3 , Group : 14.

As per the given configuration of the element M,

• M : 2 , 8 , 4

So, total number of electrons in M

$= 2 + 8 + 4$

$= 14$

Now, putting the electronic configuration with respect to orbitals:

$M : 1 {s}^{2} 2 {s}^{2} 2 {p}^{6} 3 {s}^{2} 3 {p}^{2}$

So, we can say:

• Period : 3

• Group : 10 + (valence electrons) = 10+4 = 14

• M is a p group element.

Hope It Helps.
