Answer #1

Matter can be classified into two categories

1. pure substances 2. mixtures

1. these pure substances are further classified into compounds and elements.

2. where as mixtures are physically combined structures which can be separated into their original components.

now compound is substance which is combination of two or more elements joines in different praportions.

Element is substance which can not be broken down into simpler substances with another means.
