I assume you are talking about the Alkali metal group which in fact would readily loose their outer electron to form a 1+ cation (have a full valence electron shell).
The outer electron configuration of an alkali metal is one electron in the s subshell. This electron is easily lost to form a cation with a full valence shell, resulting in the high reactivity of alkali metals.
The oute (valence) shell of the alkali metals contains just one electron
1 valence electron
alkali metal
Alkali metals have 1 electron in their outer shell.
Hydrogen is grouped with alkali metals because it has similar chemical properties, such as having one electron in its outer shell and being reactive. However, hydrogen is not a true alkali metal as it does not readily form a cation with a 1+ charge like the alkali metals do.
The alkali metals exist in group one of the Periodic Table; as such, they are in the s-block. The electron configuration for each alkali metal ends in ns1. When represented in an Aufbau diagram, the outer shell electron has an "up" spin. Because of their single outer shell electron, alkali metals react well with halogens.
the alkali metals have 1 electron in their outer most shell. in order to obtain a full outer shell they have to lose this electron. so when they react with another metal they lose this electron and the outer most shell.
since all the alkali metals have one electron in there outer most shell so there valency is always one & they are the most electropositive elements in the periodic table.they loose one electron from there outermost shell to form one positive charged cations.

Neither of these metals hold onto their outer electron (singular, as they are alkali metals) very strongly. Relatively speaking though, lithium holds onto its outer-most electron more strongly than Sodium does.
