- By alkali metals losing their outermost electron, they can form stable ions with 1+ charge, as it is relatively easy to lose one electron. Hence, why Alkali metals are the most reactive metals.
- Because they can either lose or gain 4 electrons
1. The Alkali metals lose their electron because they create stable ions that have 1+ charge. Since it is easy to get one electron lost, this is why the Alkali metals are reactive metals.
