Question

Lithium, a group 1 element with an electron configuration of 1s22s1, will form a _____ ion in a chemical reaction.

Answer 1

Lithium, a group 1 element with an electron configuration of 1s22s1, will form a cation ion a chemical reaction. It is so, because as mentioned before it is part of group 1 elements and these tend to lose electrons from other element they react with. In this way, as they lose electrons, the final charge of the ion is possitive.

Answer 2

Being part of the 1A group, in a chemical reaction, Lithium will produce an ion with a charge of +1. This type of ions are called cations because of the positive charge. In this sense, during chemical reaction, lithium will release one of its ions.
