Question

The element that exhibits both covalency and electrovalency
A) Ne
B) Na
C) Ba
D) Cl​

Answer 1

Answer:

D) Cl

Explanation:

it can form both the ionic and covalent as it can shares and receive the electrons.

Answer 2

Answer:

The correct answer is option D) Cl​.

Explanation:

Chlorine with metals forms an electrovalent bond (or) ionic bond and with non-metals forms covalent bonds hence it exhibits both electro valency and covalency

For example:

• "Ne" do not form bonds due to stable octet configuration and hence did not shows valency.
• $\mathrm{Na}$ and $\ \mathrm{Ba}$ are metals, they form only ionic bonds and exhibit electro valency.

Therefore, the correct answer is option D) Cl​.
