Beryllium is the chemical element with atomic number 4. Its symbol is Be.
Chemical Properties
Beryllium melts at 1560 Kelvin (K) and boils at 2742K. In its solid elemental form it is metallic.
Isotopes
There is only one stable isotope of beryllium, 9Be. A second isotope, 10Be, is commonly produced in Earth's atmosphere and accumulates at the surface of the soil. 10Be currently has a half-life of 1.36 million years and decays through proton capture to form a boron isotope. Evolutionists claim that 10Be abundance can be used to measure the age of geological features through radiometric dating.
