I need an answer ASAP

If an atom is highly reactive, a metal, and has one valence electron, what group/family does it belong to? (Name and number)

Respuesta :

Answer: Alkali metals, group 1

Explanation: Group 1 means 1 valence electron. This group is called alkali metals, which indicates that it is a metal. They are highly reactive because only 1 electron needs to move to bond with something (since it only has 1 valence electron)
