Answer:
The answer is option 1.
Explanation:
Lithium is a Group 1 element. So the correct charge for lithium should be Li+.
(a)[tex]Li^{2+}[/tex]
Answer is (a)[tex]Li^{2+}[/tex]
As lithium has only one valence electron, it will lose one electron to form a cation with charge 1+ . Thus the correct Li ion is [tex]Li^{1+}[/tex]
