How is a covalent bond formed? an atom gives one or more of its electrons away to another atom. two atoms share a pair of electrons in their outer shell. valence electrons move freely through a set of positively charged ions. two atoms chemically react to create a single atom of another element.

Covalent bonds form when atoms share their valence electrons with other atoms to become a more stable molecule.

Explanation: Atoms form covalent bonds as a result of the Octet Rule. The Octet Rule states that all atoms in a molecule need to have eight electrons in their valence shell. This rule can be satisfied by sharing, losing or gaining electrons. A covalent bond allows atoms to satisfy the Octet Rule via sharing.

the function of the protein macromolecule is to move things in and out of the cell and transport other molecules in the body. there are many functions of proteins. they are the basic building blocks of living things and are responsible for the growth and repair of body cells and tissues.
