Question

a. Explain how the element sodium is
monovalent.​

Answer 1

Answer:

This is how  :

Explanation:

Monovalent element refers to those which have  valency one .

Electronic configuration of sodium = 2 , 8 , 1

∴ You can say that sodium is a monovalent element which loses one electron to achieve stable electronic configuration of the nearest noble gas Neon (2 , 8)

Answer 2

$\huge{\underline{\underline{\sf{Answer:-}}}}$

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.
