The total black bear population is estimated to be between 600,000 to 700,000 (excluding baby cubs). Habitat distribution information suggests about 55% live in Canada, 40% live in the United States, and 5% are in Mexico (accurate population facts south of Mexico unknown).
The six electrons can't all go around the nucleus at the same distance-only two electrons can fit in the inner shell. So some of the electrons have to go farther away from the nucleus. A carbon atom has two shells, with two electrons in the inner shell and four electrons in the outer shell.But that outer shell could hold as many as eight electrons-it's not full.ost of what we use for fuel is made of carbon, too. Coal, gasoline, oil, and wood are all made of hydro-carbons. In the picture you can see leftover carbon dust pouring out of this truck that burns diesel fuel. It's this carbon pouring into the air that's causing global warming.
Carbon dioxide is a compound made up of the elements carbon and oxygen. Its chemical formula is CO2, which specifies that one molecule of CO2 contains one carbon atom and two oxygen atoms. Continue Reading.
