What is the study of matter called?

All matter is ultimatelycomposed of atoms. Matter which consists of only one type of atom is called anelement while matter whose constituent particles contain atoms of more than oneelement is called a compound. Elements can be classified in many different ways.Some classifications rely on simple physical properties while others alsoincorporate chemical properties. One useful classification of elements is intometals vs non-metals.

How does a compound differ from an element?

COMPOUND differs from an element in that an element contains only a singletype of atom while a compound consists of smallest units which contain at leasttwo different types of atom (i.e. atoms of at least two different elements) joinedtogether by chemical bonds. Compounds always contain atoms of their constituentelements in the same numerical ratio regardless of how the compound wasprepared. Consequently analysis of any pure compound always returns the sameresult. Therefore a compound when pure is HOMOGENEOUS.Manycompounds exist as discrete molecules. The smallest unit of the compound carbondioxide is the carbon dioxide molecule, each of which consists of one carbon atombonded to two oxygen atoms - this molecule is the smallest particle of carbondioxide that can exist. The ratio of one carbon atom to two oxygen atoms in themolecule of this compound applies equally well to the carbon dioxide which mayoriginate from burning of natural gas or petrol or from chemical reactions such aswhen an acid is mixed with a substance such as limestone or washing soda.Carbon dioxide molecules always consist of one carbon atom bonded to twooxygen atoms regardless of the source of the compound.

What is a solution made of?
