<p>A chemical bond may be defined as the force of attraction between any two atoms, in a molecule, to maintain stability.</p> Signup and view all the answers

<p>The three methods in which atoms can achieve a stable configuration are: (1) The transfer of one or more electrons from one atom to the other to form an electrovalent (or an ionic) bond, (2) The sharing of electrons between atoms to form a covalent bond, and (3) The presence of a metallic bond, where electrons are shared among a large number of atoms.</p> Signup and view all the answers
