Ionic bond is formed due to the transfer of some electrons from one atom to another

All matter is made up of tiny building blocks that are known as atoms. Atoms make up elements, which are the substances found naturally on Earth or in the atmosphere that can't be further chemically broken down. Atoms of the different elements bond with each other in order to form molecules and compounds.

An ionic bond is formed by the complete transfer of some electrons from one atom to another. The atom that is losing one or more electrons becomes a cation which is a positively charged ion. The atom that is gaining one or more electron becomes an anion which is a negatively charged ion. When the transfer of electrons occurs, an electrostatic attraction between the two ions of opposite charge takes place and an ionic bond is formed.

water molecules' fluid interactions. Individual H2O molecules have a V-shape and are made up of one oxygen atom and two hydrogen atoms (shown in white) (depicted in red). Hydrogen bonds allow adjacent H2O molecules to temporarily connect (depicted as blue and white ovals).

In each H2O molecule, the hydrogen (white) and oxygen (red) atoms are held together by powerful connections known as covalent bonds. When two atoms share electrons with one another, as is the case here with oxygen and hydrogen, covalent bonds are created. The V-shaped H2O molecule takes on a little different charge on each end because oxygen and hydrogen draw the shared electrons in different ways.
