1 electron in the s orbital
Just one.
A metal in the alkali metal family has one valence electron where as a metal in boron family has three valence electrons. It is easy to remove one valence electrons than three. So alkali metals will be more reactive.
Group 1 or alkali metals
they all have a differnet number of electrons, but all have a charge of 1-
Bismuth is not an alkali metal.
Radium is a member of the group 2 (alkaline earth metals) of the periodic table of Mendeleev; the other members are beryllium, calcium, magnesium, strontium, barium. Radium is also a radioactive element.

It is al alkaline metal (not an alkali metal).
It is al alkaline metal (not an alkali metal).

Group 1 or alkali metals
The chemical element "sodium" is an alkali metal.
One
they all have a differnet number of electrons, but all have a charge of 1-
Lithium is the smallest(first) member of Group 1 , the Alkali metals.
The alkali metal, sodium, is an element.
All alkali earth metals have 2 valence electrons.
