The science that deals with the composition, structure, and properties of matter and how matter changes under different conditions
The study of substances that contain the element carbon
The branch of chemistry dealing with compounds that do not contain the element carbon, but may contain the element hydrogen
Any substance that occupies space and has mass
The simplest form of chemical matter; can't be broken down without a loss of identity
The particles from which all matter is composed
Formed by joining two or more atoms chemically
Contain two or more atoms of the same element that are united chemically
Chemical combinations of two or more atoms of different elements that are united chemically
Have definite size and a definite shape
Have a definite size but a definite shape
Do not have a definite size or a definite shape
Characteristics that can be determined without a chemical reaction and that do not cause a chemical change in the identity of the substances
Characteristics that can be determined only with a chemical reaction and that cause a chemical change in the identity of the substance
Change in the form or physical properties of a substance without the formation of a new substance
Change in the chemical composition of a substance, in which a new substance are formed having properties different from the original
Combination of two or more atoms of different elements united chemically; fixed chemical composition, definite proportions, distinct properties
