i'm talking about beryllium's stable isotope, Be-9what are it's uses?
Of all the metals, beryllium has one of the highest melting pointIts modulus of elasticity is approximately 1/3 greater than steelIt is nonmagnetic, resists attack by concentrated nitric acid, is an excellent thermal conductivity and it is highly permeable to X-raysAt a standard temperature and pressure it resists oxidation when exposed to air As an alloying agent in the production of beryllium copperSheets of beryllium foil are used with X-ray detection diagnosticsFor the reproduction of microscopic integrated circuits in the field of X-ray lithographyAs a neutron reflector and moderator in nuclear reactorsIn nuclear weapons to surround the plutonium sphere which reduces the mass of the sphereIn neutron sources where it is mixed with an alpha emmiter like polonium 210, radium 226, or actinium 227In the making of gyroscopes, various computer equipment, watch springs and instruments that requires light-weight, rigidity and dimensional stabilityIt is also required in those applications where an excellent head condutor, with high strength and hardness and with a very high melting point is neededEven it should act as an electrical insulatorOnce used in fluorescent lighting tubes.
Calcium would have 2 dots, because it's electron configuration is 2-8-8-2 All of the elements in the second group of the PT have 2 valence electrons.
