Boron is a chemical element with atomic number 5 which means there are 5 protons in its nucleus. Total number of protons in the nucleus is called the atomic number of the atom and is given the symbol Z.The total electrical charge of the nucleus is therefore +Ze, where e (elementary charge) equals to 1,602 x 10-19 coulombs.

WebBoron trifluoride or boron trichloride for example use something called backbonding to create stability. Backbonding is when an electron-rich atom in a bond donates some electron density to the electron-poor atom. In these boron compounds the central boron atom has an unfilled unhybridized p orbital perpendicular to the plane containing the atoms.
