a covalent chemical bond is one in which ...
○ electrons are removed from one atom and transferred to another atom so that the two atoms become oppositely charged.
○ protons and neutrons are shared by two atoms so as to satisfy the requirements of both atoms.
○ outer - shell electrons of two atoms are shared so as to occupy the outer electron shells of both atoms.
○ outer - shell electrons of one atom are transferred to fill he inner electron shell of another atom.

Explanation:

A covalent bond is formed when outer - shell electrons of two atoms are shared to fill their outer electron shells. The first option describes an ionic bond. Protons and neutrons are not shared in bonding. Transferring outer - shell electrons to fill inner - shell is not how covalent bonds form.

Answer:

outer - shell electrons of two atoms are shared so as to occupy the outer electron shells of both atoms.
