Question

the outermost shell of an element with 3 shells contain 8 electrons

a.write the elctronic configurations of the element

b.does the element take part in chemical reaction .give reason​

Answer 1

Answer:

Electronic Configuration:2,8,8

Name of the element: Argon

Explanation:

No the element will not take any part in the chemical reaction as it has completed its octet.

Answer 2

Answer:

a. The electronic configurations of the element is 2,8,8.

Electronic configuration the element is: $1s^2,2s^2,2p^6,3s^2,3p^6$

b. The element is Ar. Elements in group VIII A (He, Ne, Ar, Kr, Xe, and Rn) are called noble gases or rare gases. No, Argon never take part in an chemical reaction as it has octate electronic configuration i.e. it has complete M shell by 8 electrons. So electrons cannot be donated or excepted by it.
