Answer:

lithium ,sodium

Explanation:

Elements with valency 1 are those elements which can either gain one electron or lose one electron in order to have stable electronic configuration.

An example is chlorine with atomic number 17. It has electronic

configuration as 2,8,7.

Hence, it accepts one electron to form Cl

and attains stable octet configuration. Such elements are non-metals.

Whereas, elements like sodium with atomic number 11 has electronic configuration as 2,8,1.

It is easier to lose the outermost electron to become stable and form Na

+

. Such elements are metals.
