The metal is steel-gray in color, very light, with one of the highest melting points of the light metals. Its modulus of elasticity is a third higher than that of steel.
Sep 20, 2019· Beryllium is both a common participant and a product in many nuclear reactions. It is present in the core of stars and it undergoes nuclear fusion to produce heavier elements. Beryllium was used in the discovery of the atomic structure and the discovery of the neutron by James Chadwick. Chemical Properties of Beryllium
Due to its physical properties, beryllium is useful as a hardening agent in alloys, making aerospace material, and used as a filter for radiation. Beryllium is not used for commercial use due to the harmful effects when it is inhaled through dust particles, causing berylliosis (a …
Beryllium has no known biological role, and its dust causes chronic inflammation of the lungs and shortage of breath. Brief exposure to a lot of beryllium, or long exposure to a little, will bring on this lung condition which is known as berylliosis.
Helium (He) and Be2+ ion (not beryllium element) have the same number of valence electrons (two). But their properties are different as they differ in the number of protons (2 for helium, 4 for ...
