Chemistry is commonly referred to as a central science because it usually merges with other sciences such as biology and physics. Chemistry mainly focuses on the interactions between atoms. Notable chemists include John Dalton, who proposed the modern theory of atoms, and Antoine Laviosier, who developed the principle of conservation of mass.
