Answer:
It has 1 electron in its last shell which means it has 1 valence electron. In order to get stability by acquiring nearest noble gas configuration. Sodium prefers to loose 1 electron. Hence, we say that sodium has a valency of one and is thus monovalent

Explanation:
Considering the sodium ion, which is represented by Na+, then it has avalency of +1, having lost an electron. ... Of electrons in outer shell are called valence electrons and same is the valency. Here no. of electrons in outer orbital is 1 so thevalency of sodium is 1.
