Question

write about covalent bonds with example​

Answer 1

Answer:

Example: Carbon dioxide molecule has one carbon atom with six valence electrons and two oxygen atom with four valence electrons. ... Therefore the atoms share two electrons each to form the oxygen molecule. Since two electron pairs are shared there is a double bond between the two oxygen atoms.

Answer 2

Answer:

Covalent Bond

Explanation:

A covalent bond in chemistry is a chemical link between two atoms or ions in which the electron pairs are shared between them. A covalent bond may also be termed a molecular bond. Covalent bonds form between two nonmetal atoms with identical or relatively close electronegativity values.

A covalent bond is a type of chemical bond characterized by the joint sharing of electron pairs between atoms. Covalent bonds form when atoms share valence electrons with other atoms to achieve a full shell of outer electrons.

e.g. H2, O2, CH4 etc.
