Answer 2

Explanation:

Elements can be determined by the amount of the electrons in their last shell (known as their outer shell). The amount of electrons in their outer shell determines their group, and hence their electronic properties. The alkaline metals all have 1 electron in their outer shells. They all react vigorously with water.
