Acovalent bond is formed by the following process: a. loss of an electron by one atom to another b. sharing of an electron by two atoms c. sharing two electrons by two atoms d. gaining or losing two or more electrons by an atom

Answer : The correct option is, (C) sharing two electrons by two atoms

Explanation :

Covalent bond : It is defined as the bond that is formed when sharing of electrons takes place between the atoms.

This is usually formed between two non-metals.

As we know that the chlorine is a non-metal and has 7 valence electrons.

A covalent bond is formed between the two chlorine atoms by the sharing of two electron.

Ionic bond : It is defined as the bond that is formed when electron gets transferred from one atom to another atom.

This is usually formed between metal and non-metals.

As we know that the sodium is an alkali metal and has one valence electron and chlorine is a non-metal and has 7 valence electrons.

When sodium atom donates an electron to a chlorine atom then it forms an ionic compound that is sodium chloride (NaCl).

Hence, the correct option is, (C) sharing two electrons by two atoms

sorry i was late, but i don't know what assignment your talking about, i'm in flvs as well, im in earth space science. but u are behind pace bc every class should be in the 3's or 4'
