Because all alkali meals have same no of electrons (only one) in their outermost shell

Alkali metals are highly reactive and tend to form ionic compounds by easily losing their outermost electron. They are soft, shiny, and have low melting points. In reactions, alkali metals typically produce hydrogen gas and form basic solutions.
Hydrogen shares some properties with alkali metals, particularly in its ability to lose one electron to form a cation with a +1 charge like alkali metals. However, hydrogen is a nonmetal and not a metal like the alkali metals.
True. Lithium is unique among the alkali metals in terms of its physical and chemical properties. It is the lightest metal and has the highest melting and boiling points among the alkali metals. Additionally, lithium forms covalent bonds more readily compared to other alkali metals.
