Question

The electronic configuration of an element ‘X’ is 2,8,6. To which group and period of the modern periodic table does ‘X’ belong .State it valency and justify your answer in each case.

Answer 1

X is sulphur(S).

Group no. 16

Period no. 3

Valency. 2

Answer 2

PLEASE MARK IT AS BRAINLEST

X – 2, 8, 6

a) Since ‘X’ has three energy shells and period number of an element is equal to the number of energy

shells, X belongs to 3rd period.

b) X has 6 valence electrons it belongs to group 16.

c) Valency will be 2. To acquire noble gas configuration it will gain 2 electrons.
