Respuesta :

Alkali metals have one valence electron in S orbital . hence , this electron can be donate easily . thus all the alkali metals acts as reducing agent in general chemical reactions .

What are alkali metals ?

Alkali metals are the elements of group 1 in the periodic table .

It has a strong tendency to donate their valence electron in the last shell to form ionic bond .

They have least nuclear charge in their period .

Nuclear charge decreases and atomic radius increases down the group .

To prevent oxidation they are mostly stored in a oil containing jar .

The density of this group metal is very low .

General electronic configuration is ns1 .

They are good conductor of heat and electricity .

When these metals react with water  produce a alkaline solution and release hydrogen gas .

Group 1 elements includes lithium , sodium , potassium , rubidium , Caesium .
