Beryllium, Chemical Element
Beryllium is a hard, brittle metal with a grayish-white surface. It is the least dense (lightest) metal that can be used in construction. Its melting point is 1,287°C (2,349°F) and its boiling point is estimated to be about 2,500°C (4,500°F). Its density is 1.8 grams per cubic centimeter.

Beryllium – Protons – Neutrons – Electrons – Electron Configuration
Protons and Neutrons in Beryllium. Beryllium is a chemical element with atomic number 4 which means there are 4 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.

About Beryllium
From these sources, beryllium is emitted into the air and water by natural processes like erosion and by the burning of coal and oil. According to data collected by the Environmental Protection Agency (EPA), the average concentration of airborne beryllium in the U.S. is very small (0.03 nanogram/cubic meter—a nanogram is one-billionth of a gram).
