Document Summary
Any material in universe with mass and occupies space; solid, liquid, or gas. Law of conservation of matter: matter may be transformed from one type into another, but cannot be created or destroyed. Atom is the core: protons, electrons, neutrons: element: consist of the same atoms. Mercury, potassium, oxygen: compound: 2 or more different elements. Earths most abundant chemical elements, by mass: oxygen heaviest in earth"s crust, oceans, and organisms. Atoms de ned by number of protons: atomic number. Isotope: atoms with same # of protons but different # of neutrons. Polar molecule: net negative charge at one end and net positive charge at the other. Very strong cohesion : ability to for molecules to hold onto one another: important for solute transport in plants. Very high heat capacity: water holds onto heat over long periods of time: helps stabilize our climate. Ice is less dense than liquid water since ice oats.
