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.
A molecule of the compound carbon dioxide contains one atom of the element carbon and two atoms of the element oxygen. Each oxygen atom shares a double bond with the carbon atom. Carbon is the sixth element in the periodic table and occurs in pure form as coal and diamonds.Oxygen, element eight, is a gas that makes up about 21 percent of the atmosphere. Living things take in oxygen and release carbon dioxide. The oxygen helps turn food into energy, creating carbon dioxide as a byproduct.arbon is the sixth element in the periodic table and occurs in pure form as coal and diamonds.
