Ionic Bonding

Chemical bonding resulting from the transfer of one or more electrons from one atom or a group of atoms to another.

Oxidation Numbers

Arbitrary numbers that can be used as mechanical aids in writing formulas and balancing equations, for single- atom ions they correspond to the charge on the ion, more electronegative atoms are assigned negative oxidation numbers (also called Oxidation states).

Active Metal

Viscosity

Resistance offered by the molecules of a liquid to flow is termed as viscosity.
