Elements any substance that contains only one kind of an atom is known as an element because atoms cannot be created or destroyed in a chemical reaction. Elements, compounds & mixtures elements type of matter by either physical or chemical means, and can exist as either atoms of two or more atoms of the same. Chemistry is the scientific discipline involved with compounds composed of atoms, ie elements, and molecules, ie combinations of atoms: their composition. In this inaugural episode of crash course chemistry, we start out with one of the biggest ideas in chemistry ever - stuff is made from atoms. Chemical bonding chemical compounds are formed by the joining of two or more atoms a stable compound occurs when the total energy of the combination has lower energy than the separated. Generally were deﬁned as those compounds lacking carbon atoms organic chemistry occupies a central role in the world around us, as we are surrounded.

States of matter gases, liquids and solids are all made up of microscopic particles, but the behaviors of these particles differ in the three phases. Any substance consisting of two or more different types of atoms (chemical elements) in a fixed proportion of its atoms (ie, stoichiometry) can be termed a chemical compound the concept.
