Question

Explain how the element sodium is monovalent​

Answer 1

Answer:

Sodium is metal which has atomic number 11. It has 1 electron in its last shell which means it has 1 valence electron. ... Sodium prefers to loose 1 electron. Hence, we say that sodium has a valency of one and is thus monovalent.

Answer 2

Answer:

Because of electronic configuration

Explanation:

Sodium Atomic number=11

Electronic configuration=1s2 2s2 2p6 3s1

In outer shell we had only one electron

outer shell electrons are called as valence electrons.

Thus Sodium is Monovalent.
