However, its very small size and somewhat higher ionization energy compared to other metals actually lead to beryllium forming primarily molecular compounds. Relevance. The different rules determine how much tax a person pays. The boron has formed the maximum number of bonds that it can in the circumstances, and this is a perfectly valid structure. For bonds that are covalent, indicate whether they are polar or nonpolar. Boron reacts with halogens to give the corresponding trihalides. In the diamond-like structure, called cubic boron nitride (tradename Borazon), boron atoms exist in the tetrahedral structure of carbons atoms in diamond, but one in every four B-N bonds can be viewed as a coordinate covalent bond, wherein two electrons are donated by the nitrogen atom which acts as the Lewis base to a bond to the Lewis acidic boron(III) centre.
