Document Summary
Chemical bonds in minerals: ionic bond, covalent bond, van der waals bond, metallic bond. : electron is lost from one atom and gained by another. : weak secondary attraction between electrically neutral molecules. : electrons drift from one atom to another. Isotopes: each type of an element, as determined by atomic weight, is called an isotope, atomic weight: number of protons + neutrons in an atom. Ex: carbon-12, carbon-13, and: radioactive isotopes: can be used to help determine the age of geologic events. Ex: carbon: radioactive decay: source of heat for driving tectonic processes, ratios of stable isotopes provide information about chemistry or temperature of seawater and.
