Living Matter and Nonliving Matter

Matter is classified according to origin or source, state and composition.

According to the origin or source, matter is classified as organic and inorganic matter. Organic matter comes from living things, while inorganic matter comes from non-living things.

Chemists have studied that all forms of matter may be classified into three general classes on the basis of their compositions. These are the elements, compounds and mixtures.

Element is a substance, which cannot be decomposed by ordinary means. Atom is the smallest part of an element that can enter into combination with other elements.

Compound is a substance, which can be decomposed into two or more simpler substances by ordinary chemical means.

Mixture is a material composed of two or more substances each of which retains its own characteristic properties. a. Heterogeneous mixture is one which has parts possessing different properties. b. Homogeneous mixture is one which has similar properties throughout. Substance is a homogeneous material composed of one particular kind of matter
