Document Summary
Carbon 12 and 13 are stable, but carbon 14 is unstable. When it rains, rain tends to rain out heavier elements than the lighter ones. Salmon are relatively enriched with heavier isotopes of nitrogen and carbon. You can use these isotopes to track the fate of different ecological components of a system. We tend to become enriched by these heavier forms of n and c as we go up the food chain. Electrons may not be shared equally (polarity: unequal charge sharing throughout the compound) Adhesion of water to charged surfaces drives capillary action (water up stems of plants) Water is the most dense at 4 degrees c. Bohr proposed that every atom possesses an orbiting cloud of tiny subatomic particles called electronics. Rutherford carried out the gold foil experiment which led him to propose the idea of a nucleus in an atom. The mass of atoms and subatomic particles is measured in units called daltons.
