Document Summary
The residence time is defined as the total quantity of the material divided by the rate of input or removal: periodic table. All elements in columns react in the same fashion. The last column, column 8, are the inert elements. Mass of atom found in the nucleus as either protons or neutrons. Electron sharing or exchange responsible for forming compounds from individual elements. Water molecule is polar; i. e. , it has a positive and negative side. Polarity of water is responsible for hydrogen bonding (what is h bonding?) Which is responsible for giving water a structure . The addition of salt to water alters its properties: Radioactivity is an effort the atom makes to attain a stable state by altering the ratio of neutrons. The rate of decay to some stable element is termed the half life. Typical radioactive isotopes and their half lives are listed below.
