My element name is Boron. My slogan is my symbol is B! I'm right at the top of Group IIIB! When the first time seen my element is in the PT. boron symbol is B and is in Group IIIB. Two of them are having B. It looks very simple. I think that is very fun idea, so I just use this for my slogan. Boron is a chemical element with chemical symbol B and atomic number 5. It is in period 2, Group 13 element that has properties which are nonmetals. The name boron comes from the Arabic and Persian words for borax. Boron was discovered by Sir Humphrey Davy, Joseph-Louis Gay-Lussac, and L.J. Thénard at 1808 in England, France. Boron exists in the earth's crust to the extent of only about 10 ppm. Boron is solid and black. It is very hard and in extremely pure form is nearly as hard as diamond, but much too brittle for practical use. The atomic mass is 10.811g. Density is 2.34g/cm^3. Melting point is 3769︒F and boiling point is 7101︒F.Siilicon is the closely related elements with boron. Boron is used in pyrotechnics and flares to produce a green color. Boron has also been used in some rockets as an ignition source. Boron is used to control nuclear reactions. It is an excellent neutron absorber. Alloyed with steel or reacted with carbon, titanium or zirconium, it is used in control rods for nuclear reactors Boron is an essential nutrient for all green plants Bibliography:
