Chemical bond: The force of attraction that holds different components like atoms, ions, etc. together in different chemical species is called a chemical bond.
Covalent bond: A chemical bond in which two atoms share an electron pair is called a covalent bond. Each combining atom contributes at least one electron to the shared pair.
Ionic bonding: Ionic bonding involves the transfer of electrons from one atom or molecule to another. In ionic bonding, one atom loses an electron and another atom gains an electron. This results in positively and negatively charged ions.
There are two types of bonds formed between atoms in a molecule, ionic and covalent.
Ionic and covalent bonds depend on the nature of the 4 atoms, i.e. metallic elements or nonmetallic elements.
If one atom in the bond is a metal and the other atom is a nonmetal, it is an ionic bond.
If both atoms in the bond are nonmetals, it is a covalent bond.
Carbon tetrachloride (CCl4) is known as a covalent compound because it contains four non-polar covalent bonds between carbon and chlorine.
