Document Summary

Atoms, molecules, elements, compounds, mixtures, and states of matter. Forms of matter: sand, rock, wood, ash, living tissue. About 110 substances can"t be split into simpler stable components=elements. Most substances consist of two or more elements chemically combined. Elements are the fundamental types of matter. Body consists of water the most and that"s why our body consists 64. 6% of oxygen. Ductile: can be drawn into a wire. Conductive: good conductor of heat and electricity. Compounds: sodium, potassium, calcium, magnesium, barium, radium. Ex: hydrogen, helium, carbon, nitrogen, oxygen, fluorine, neon, silicon, Matter can be divided indefinitely but consists of discrete units= atoms. Atoms of different elements have diameters in the range of a few tenths of a nanometer. Human red blood cell = 10000x larger than an atom. All atoms of a particular element are equal in size and in most aspects of their behavior.
