            Water molecules have a polarity, which allows them to be electrically attracted to other water molecules and other polar molecules by weak chemical bonds known as Hydrogen Bond.

                     Hydrogen Bond Interactions are those interactions which are formed between a partial +ive hydrogen atom bonded directly to most electronegative atoms (i.e. Fluorine, Oxygen and Nitrogen) of one molecule interacts with the partial -ive most electronegative atom of another molecule. These interactions are considered the strongest intermolecular interactions and are responsible for many stronger physical properties of water like, boiling point, viscosity, solubility e.t.c.

                       Attached figure shows the hydrogen bond interactions (green dashed lines) between water molecules. The partial charges are shown in red color.

each chemical family is represented as a group or column on the periodic table. based on chemical properties, there are 6 types of chemical families. group 1 represents alkali metals, group 2 represents alkaline earth metals, groups 3 to 12 represent transition metals, groups 13 to 16 represent non-metals and other metals, group 17 represents halogens and group 18 represents noble gases.
