Question

Why is CO2 a covalent compound?

Answer 1

Answer:

carbon dioxide

Explanation:

carbon dioxide

Answer 2

Answer:

Carbon dioxide is covalent bond.

Carbon cannot form ionic bond because in the simplest sense carbon can neither lose 4 electrons for stablisation (Due to it's strong attraction to the nucleus) nor gain 4 electrons (Since it's small nucleus with 6 protons cannot manage extra 4 electrons).

Another thing to remember is that; talking in the most basic sense

Ionic bonds generally occur only between a metal and a non-metal

Metallic bonds between two metals

And COVALENT BOND generally between two non-metals.

To sum up, Carbon being a non-metal with a small, tightly held together atom bonds with two atoms of another non-metal Oxygen thereby mutually sharing electrons and forming one molecule of Carbondioxide (CO2).
