Alkali metals
Explanation:
All alkali metals have 1 valence electron, and they want to lose it, because if they do, they will have 8 valence electrons, which will make them inert.
When an atom lose an electron, the atom becomes a cation, because the atom will have one less electrons than protons.

The alkali metals easily loose an electron and form a +1 cation.

The periodic table is arranged in groups and periods. The elements in the same group have the same number of valence electrons and similar chemical reactivity. This is why groups of elements are also called families of elements.

The group of the periodic table which its members easily loose electrons and form a +1 cation are the alkali metals.
