The number of atoms of the element per 1 million atoms of the Earth’s crust. It is defined as being the charge that an atom would have if all bonds were ionic. Beryllium is an element with an atomic number of 4 in the periodic table. Beryllium is a chemical element with atomic number 4 which means there are 4 protons in its nucleus. The number of electrons in an electrically-neutral atom is the same as the number of protons in the nucleus. A French chemist name Louis Nicolas Vanquelin discovered the Alkali Earth Metal Beryllium in 1798. The element has one of the highest melting points among the light metals. Analysis of the oxygen in these gems enables their source to be identified because the isotope ratio of oxygen-18 to oxygen-16 varies according to where the mineral is found. It is used in metallurgy as a hardening agent and in many outer space and nuclear applications. Atomic radius, non-bonded "Didymium" he answered cryptically, and then noticing my blank look, he added "Cuts out the light. Wiki User Answered . Have you identified the position of Beryllium in periodic table? You do not have JavaScript enabled. Beryllium is a silver-grey metal and is hard and brittle at room temperature. CAS number A bivalent element, beryllium is a steel grey, strong, light-weight yet brittle, alkaline earth metal. Brief exposure to a lot of beryllium, or long exposure to a little, will bring on this lung condition which is known as berylliosis. The amount of this isotope in marine sediments laid down in the last ice age was 25% higher than that in post-glacial deposits. Electronegativity (Pauling scale)The tendency of an atom to attract electrons towards itself, expressed on a relative scale. Emerald and aquamarine are precious forms of beryl. The name beryllium was adopted officially in 1957. Beryllium is a hard, grayish metal naturally found in mineral rocks, coal, soil, and volcanic dust.
