It is a metal and has a high melting point. At ordinary temperatures, beryllium resists oxidation in air. Beryllium compounds are very toxic. Its ability to scratch glass is probably due to the formation of a thin layer of the oxide. ]]> 2017-04-26 21:41:17 UTC https://padlet.com/3011602/4n86zv79t0gg/wish/168507036 Californium 3011602 https://padlet.com/3011602/4n86zv79t0gg/wish/168507827 Californium is a radioactive rare earth metal named after the state of California and the University of California (USA). Californium-252 is a strong neutron emitter and one microgram emits 170 million neutrons per minute, making it a biological hazard.]]> 2017-04-26 21:50:22 UTC https://padlet.com/3011602/4n86zv79t0gg/wish/168507827 copper 3011602 https://padlet.com/3011602/4n86zv79t0gg/wish/168507962 Copper appears in the periodic table at the top of Group 11 above silver and gold. Collectively these are sometimes referred to as the coinage metals, although in modern times these metals are used less frequently than in the past.

Fluorine is the most electronegative and reactive of all elements. It is a pale yellow, corrosive gas, which reacts with practically all organic and inorganic substances. Finely divided metals, glass, ceramics, carbon, and even water burn in fluorine with a bright flame. It is not uncommon to see fluorine spelled incorrectly a]]> 2017-04-26 21:55:49 UTC https://padlet.com/3011602/4n86zv79t0gg/wish/168508281 actnium 3011602 https://padlet.com/3011602/4n86zv79t0gg/wish/168508368 Actinium is dangerously radioactive. The chemical behaviour of actinium is similar to that of the rare earths, particularly lanthanum. It is found naturally in uranium ores and actinium is 150 times more radioactive than radium.]]> 2017-04-26 21:57:03 UTC https://padlet.com/3011602/4n86zv79t0gg/wish/168508368 irdium 3011602 https://padlet.com/3011602/4n86zv79t0gg/wish/168508457
