Concept introduction:

The principles of chemistry deal with the study of substances and the energy related with their change. Usually, the mass associated with everything is referred as matter. Moreover, matter can be viewed as macroscopic and microscopic samples. The view point of matter at particulate level is tiny to observe, models are generally used to represent particles. In common, chemists use models of atom and molecules to represent tiny particles based on experimental data. Commonly, the chemical compounds are made up of polyatomic ions and the ratio of positive to negative ions present in the substance is expressed as formula of ionic compound.
