CHEMISTRY

Beryllium is chemical element with the symbol Be and atomic number 4. Beryllium is found naturally only combined with other elements in minerals. Notable gemstones which contain beryllium include Beryl that has aquamarines and emeralds and Chrysoberil (Alexandrite and //Cat's eye//). The free element is a steel-grey, strong, lightweight brittle alkaline earth metal. It is primarily used as a hardening agent in alloys, notably beryllium copper. Structurally, beryllium's very low density (1.85 times that of water), high melting point (1278 °C), high temperature stability, and low coefficient of expansion with temperature, make it in many ways an ideal aerospace material, and it has been used in rocket nozzles and is a significant component of planned space telescopes. Because of its relatively high transparency to X-rays and other ionizing radiation types, beryllium also has a number of uses as filters and windows for radiation and particle physics experiments. Name of the element: Beryllium Symbol of the element: Be Atomic number: 4 Atomic mass: 9.012182 amu Element is use for: spacecraft, missiles, and aircraft Where was discovered? It was discovered from the mineral Beryl. Who discovered Beryllium? It was discovered by Fredrich Wohler. 1. How might understanding how to use the Periodic Table be useful? The periodic table was useful an is useful to classify the elements by atomic mass and be group by characteristics too. 2. Compare and contrast your knowledge before and after your research on your element. I think it was make in laboratories. It is made naturally in the earth.
