What is a carboxyl and carbonly group? I'm confused. If COOH is part of the carbon chain, why would one Oxygen atom have one double and one single covalent bond in skeleton form?

A carbonyl group is just the C=O and there are still two attachment points. If both are to a different carbon, the chain continues.
If you have COOH, you've reached the end of the carbon chain in that direction. There's a carbonyl group, but one of the attachments to C is OH...so no more chain.
On the other part of your question, it's generally considered that both oxygens are singly connected to the common C, and each also shares the other bond. Sometimes it's drawn as O==C----OH <--> HO---C==O (a resonance hybrid).

All I know is Carboxyl groups are one of the things in Amino acids.
