Question

explain the mono valency of the element sodium​

Answer 1

Sodium is metal which has atomic number 11. 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. ... Hence, we say that sodium has a valency of one and is thus monovalent.

Answer 2

Answer:

Sodium has one electron in its valence shell and needs to remove it to attain noble gas configuration. So, it gets ionizes and gives one electron to another compound to form a compound. Thus, it has a valency of 1 and is called as a monovalent atom
