Answer: c. Model A shows the sharing of electrons and model B shows the formation of ions.
The octet rule is a chemical rule of thumb that reflects the theory that main group elements tend to bond in such a way that each atom has eight electrons in its valence shell giving it the same electronic configuration as a noble gas.The rule is especially applicable to carbon nitrogen oxygen and the halogens but also to metals such as sodium or magnesium.
Molecular orbital (MO) theory uses a linear combination of atomic orbitals (LCAO) to represent molecular orbitals resulting from bonds between atoms. These are often divided into three types bonding antibonding and non- bonding .A bonding orbital concentrates electron density in the region between a given pair of atoms so that its electron density will tend to attract each of the two nuclei …

In chemistry valence bond (VB) theory is one of the two basic theories along with molecular orbital (MO) theory that were developed to use the methods of quantum mechanics to explain chemical bonding .It focuses on how the atomic orbitals of the dissociated atoms combine to give individual chemical bonds when a molecule is formed. In contrast molecular orbital theory has orbitals that cover …
