Properties

Home Chemistry Properties Page 2
Properties, physical and chemical property are considered as a key to understanding chemical elements (atom, molecule), substances, or matter present in our earth environment in science. The appearance, color, order, atomic and molecular weight, and density, etc are considered as the fundamental physical properties of atoms and molecules but chemical properties include ionization energy, electron affinity, hydration enthalpy, electronegativity, chemical bonding, etc. In learning chemistry, we discuss some topics related to the physical and chemical properties of atom, molecules, or compounds.
