Question

why are alkali metals highly reactive in air?​

Answer 1

Explanation:

Alkali metals are highly reactive at standard temperature and pressure and readily lose their outermost electron to form cations with charge +1. All the discovered alkali metals occur in nature.

Answer 2

Answer:

The alkali metals are all shiny, soft, highly reactive metals at standard temperature and pressure and readily lose their outermost electron to form cations with charge +1. ... All the alkali metals react with water, with the heavier alkali metals reacting more vigorously than the lighter ones. that's why they are highly reactive in air
