Boron Symbol – B Group – Semi-metal Atomic Mass – 10.811 Discovered by - Sir H. Davy, J.L. Gay-Lussac, L.J. Thénard Year - 1808

Symbol – B

Group – Semi-metal

Atomic Mass – 10.811

Discovered by - Sir H. Davy, J.L. Gay-Lussac, L.J. Thénard

Common Uses Boron is used in pyrotechnic flares to provide a distinctive green color, and in rockets as an igniter. Boron-10 is used as a control for nuclear reactors, as a shield for nuclear radiation, and in instruments used for detecting neutrons. Used with titanium & tungsten to make heat resistant alloys for jets & rockets.

Aluminum Information Aluminum is to reactive to occur in nature by itself. The most common ore is Bauxite (Al 2 O 3 .2H 2 O) In its purest form, Aluminum is soft and weak, so alloys with small amounts of copper, magnesium, silicon, and manganese are used. Aluminum is the most abundant metal and third most abundant element in the Earth’s crust.
