**Exercise 8.27: Ground-State Electron Configurations**Write the ground-state electron configurations of the following ions:- (a) Li⁺- (d) F⁻- (g) Se²⁻- (k) Sn²⁺- (n) Pb²⁺This exercise is designed to help students practice writing electron configurations, particularly focusing on ions' gain or loss of electrons.

“Since you have posted a question with multiple sub-parts, we will solve first three subparts for you. To get the remaining sub-part solved please repost the complete question and mention the sub-parts to be solved.”. To write the ground-state electron configuration of the following ions: a) Li+ Electron configuration of Li is [He] 2s1 Li on losing 1 electron forms Li+. So electron configuration of Li+ is [He] or 1s2d) F- Electron configuration of F is [He] 2s22p5 F on the gain of 1 electron forms F-. So electron configuration of F- is [He]2s22p6 or 1s22s22p6g) Se2- Electron configuration of Se is [Ar] 3d104s24p4 Se on the gain of 2 electron forms Se2-. So electron configuration of Se2- is [Ar] 3d104s24p6
