Question

What are some exceptions in chemical bonding?

Answer 1

ANSWER ----

One thing is clear: chemical bonding is basically electrical in nature, the result of attraction between bodies of opposite charge; bonding occurs when outer-shell electrons are simulatneously attracted to the positively-charged nuclei of two or more nearby atoms. Some exceptions are ---

Not all pairs of atoms can form stable bonds

Different elements can form different numbers of bonds (this is expressed as "combining power" or "valence".)

The geometric arrangement of the bonds ("bonding geometry") around a given kind of atom is a property of the element
