Boron chemical element
WebBoron 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, Semimetallic chemical element, chemical symbol B, atomic number 5.

WebBoron is a non metallic element and the only non-metal of the group 13 of the periodic table the elements. Boron is electron-deficient, possessing a vacant p-orbital. It has several forms, the most common of which is amorphous boron, a dark powder, unreactive to oxygen, water, acids and alkalis. It reacts with metals to form borides. WebBoron is quite distinct element in its group, as all other members of Group 13 are true metals. Boron exists in various allotropic forms (different forms of same elements that have different chemical and physical properties). Due to these allotropic forms, boron can exist as red crystals, black crystals or brown powder.
