Document Summary
Chemistry of the nonmetals: main group elements are grouped together because their valence electrons occupy only s or p orbitals. Insulated nanowires: carbon nanotubes long, thin, hollow cylinders of carbon atoms, scientists could make similar tubes from boron nitride: contains. Silicates: the most abundant matter in earth"s crust. 22. 3: most abundant elements in earth"s crust are oxygen (45%-50% by mass) and silicon (about 28% by mass), al, fe, ca, na, mg, k, ti, h, silicates covalent atomic solids that contain silicon, oxygen, 3-d structure of quartz (has a formula unit of sio2, generally called silica): each si atom is in a tetrahedron surrounded by four. In these minerals, the sio4 tetrahedrons occur singly, in chains, or in sheets. 4-, positively charged metal ions: when occurs singly (not bonded to other tetrahedrons), it forms. 4- polyatomic anion (which has four extra electrons that the sio4.
