Question

The electronic configuration of an element 'X' is 2, 8, 6. to which group and period of the modern periodic table does 'X' belongs. state it valency and justify your answer in each case.

Answer 1

Hey friend

Electronic configuration of element 'X'
=> 2,8,6

Now,

Valency= -2 because it contains 6
electrons in its outermost shell.

Group=>It belongs to 16th group because of its atomic number.

Period=>It belongs to 3rd period as it contains three shells.

Name = Sulphur (S)

So, the element X is sulphur.


Be perfectionist

Answer 2

sulfur has atomic no. 16 (2,8,6) is the electronic configuration
so x element will be =sulfur
it belongs in 16th group
it belongs in 3rd period and
it has valency 2
