Bonds and LewisStructures In 1916 G. N. Lewis proposed that atomscombine in order to achieve a more stableelectron configuration. Maximum stability results when an atomis isoelectronic with a noble gas. An electron pair that is shared between two atoms constitutes a Covalent Lewis Model of ChemicalBondingCovalent Bondingin hydrogen atoms, each with 1 electron,Two hydrogen atoms, each with 1 electron,can share those electrons in a Covalent share those electrons in a Covalent ::HH Sharing the electron pair gives each hydrogen anelectron configuration analogous to Bondingin F2 Two fluorine atoms, each with 7 valence electrons,Two fluorine atoms, each with 7 valence electrons,can share those electrons in a Covalent share those electrons in a Covalent bond.
