What happens in a covalent bond?

Answer 1

A covalant bond happens only between non-metals, and some metalloids.

In a covalent bond, the different elements share their valence electrons in order to achieve stability in electronic configuration.

For example, in the covalent bond of carbon dioxide (CO2), each oxygen atom will share 2 of its electrons with the carbon atom, while the carbon atom will share 2 of its valence electrons with each of the oxygen atom. In this way, all 3 atoms will achieve the stable octet structure.

Do take note that in covalent bonds, the total number of electrons shared by 2 atoms are usually equal.

Answer 2

In a covalent bond, atoms share electrons in order to achieve a more stable electron configuration. This sharing of electrons can be equal (nonpolar covalent) or unequal (polar covalent), depending on the electronegativities of the atoms involved. Covalent bonds typically form between nonmetal atoms.

Answer 3

A covalent bond is one in which outer-shell electrons of 2 atoms are shared as to satisfactorily fill the outer electron shells of both elements. (The outer-shell can have 2 electrons)
