The formal charge of an atom isthe difference between the number of valence electrons of that atom in the free state and the number of electrons given to that element in Lewis structure.

Coordinate covalent bond: A bond formed containing both coordinate and covalent bond is defined as coordinate covalent bond.

Coordinate covalent compound: A compound possesing both coordinate and covalent bond is defined as coordinate covalent compound.

Coordinate bond:A bond formed when an electron-rich atom donates one or more lone pair of electrons to the acceptor atom is defined as coordinate bond. In this type of bond, there is no mutual sharing of electrons. The atom which gives electrons...

Covalent compouns are linked together by covalent force of attraction due to which there exists less force of attraction between the binding molecules. As a result, less energy is required to break this bond. As a result, they have low melting and boiling point.

Covalent bonds are directional in nature because they are formed due to the overlapping of orbitals of two or more atoms that arrange each other in a way to maintain minimum repulsion and ensure maximum stability.

Covalent bond is defined as the bond existing between two atoms formed by the mutual sharing of electrons by the both atoms.

Covalency is the meausre of number of valence electrons that can be actively shared by an atom in forming a covalent bond.

The conditions for forming a covalent bond are as follows:

• Combining elements should have same or comparable values of Electronegativity
• Elements must have enough electrons in their valence shell (usually 5,6, or 7) in order to form a stable compound...
