ENERGY ASSISTANCE FUNDS ARE STILL AVAILABLE! Funds are still available for low income Washington County residents who could use help with their electricity, natural gas, wood, propane or oil costs. Community Actionâs Energy Assistance Program operates year round, from October 1 through September 30, not just in the winter months.
- Carbon is a nonmetal, and silicon is a metalloid. - Carbon and silicon have the same common electron configuration as s 2, p 2. But in silicon, the electrons are spread into the 3rd energy level, whereas in carbon it is only to the 2nd energy level.
It also forms compounds with the halogens, sulfur, and nitrogen and forms numerous organo-silicon compounds. Silicon is the second most abundant element of the earth's crust; it makes up about 28% of the crust by weight. Oxygen, most abundant, makes up about 47%.Aluminum, third in abundance, makes up about 8%. Silicon is widely distributed, occurring in silica and silicates, but never uncombined.ilicon is tetravalent (like carbon) in its compounds. However, in contrast to carbon, silicon exhibits the coordination number of 6 in addition to the coordination number of 4, which is explained by its large atomic volume (examples of such compounds are the silicon fluorides, which contain the grouping SiF 6 ] 2-).
