Basics
Elements are the basic building blocks of all substances and cannot be broken down into simpler substances by chemical means. Elements are made up of one type of atom and each atom contains a +charged nucleus and -charged electrons. In a chemical reaction atoms are rearranged but none are created or destroyed. Compounds are formed when atoms of two or more elements combine
