Heya!!

Here's ur answer

Corrosion: Corrosion is a breakdown of material due to chemical reaction. It is usually oxidation with air molecules.

Functional Group: A group of atom responsible for the characteristics reaction of a particular compound.

Answer 2

Answer:

1:

Corrosion is a natural process that converts a refined metal into a more chemically-stable form such as oxide, hydroxide, or sulfide. It is the gradual destruction of materials by chemical and/or electrochemical reaction with their environment.

2:

A functional group is a portion of a molecule that is a recognizable/classified group of bound atoms. In organic chemistry it is very common to see molecules comprised mainly of a carbon backbone with functional groups attached to the chain

3:

self linking property of carbon element is known as catenation
