Which Two Atoms Would Typically Form A Covalent Bond - Web covalent bonds are formed between two atoms when both have similar tendencies to attract electrons to themselves (i.e., when both atoms have identical or fairly similar ionization energies and electron affinities). Web covalent bonds are formed between two atoms when both have similar tendencies to attract electrons to themselves (i.e., when both atoms have identical or fairly similar ionization energies and electron affinities). Web for example, two hydrogen atoms bond covalently to form an h 2 molecule; When a sodium atom combines with a chlorine atom to form an ionic bond, each atom still contributes one electron to form a pair of electrons, but this pair. Each hydrogen atom in the h 2 molecule has two electrons stabilizing it, giving each atom the same number of valence electrons as the noble gas he. Web when two chlorine atoms come together to form a covalent bond, each atom contributes one electron to form a pair of electrons shared equally by the two atoms, as shown in the figure below. This partial ionic character of covalent bonds increases with the difference in the electronegativities of the two atoms. Web covalent bonds between identical atoms (as in h 2) are nonpolar—i.e., electrically uniform—while those between unlike atoms are polar—i.e., one atom is slightly negatively charged and the other is slightly positively charged.
