Question

Lithium is in Group 1A, Period 2 of the periodic table. Which statement describes the charge of the ion it typically forms?
A. It forms a cation with +2 charge.
B. It forms a cation with a +1 charge.
C. It forms an anion with a +1 charge.
D. It forms an anion with a −1 charge.

Answer 1

B. It forms a cation with a +1 charge.

Explanation: Lithium is in Group 1, so it has one valence electron. It tends to lose that electron to achieve a noble gas configuration, producing a Li+ ion (a +1 cation).
