Question

answer the following questions :
i) Write the electronic distribution in atoms of elements A and D.
ii) Element A is an inert gas, why?
) What is the valency of element c?​

Answer 1

Answer:

There is a diagram also.

Please tell

a) The outermost shell of this element is complete and the element does not gain or lose electrons to complete its outermost shell. ... Hence, A is an inert gas. (iii) Valency of element C (2, 8, 2) is 2.

Answer 2

Explanation:

(i) Electronic distribution of element A and D.

K L M

A = 2,8

D = 2,8,3

(ii) The number of electrons in the outermost shell of element A is 8. The outermost shell of this element is complete and the element does not gain or lose electrons to complete its outermost shell. Hence, A is an inert gas.

(iii) Valency of element C (2, 8, 2) is 2
