BIO 1305 Study Guide - Final Guide: Lipid Bilayer, Ionic Bonding, Cell Membrane
Document Summary
Make sure look over the following topics for the final exam. Types of questions over these topics will be concept and basic definition. If there are figures, concepts or tables listed look at them as well as text related to them. Elements: cannot be broken down chemically to other substances. Compound: contains 2 or more different elements in a fixed ratio. Essential elements: needed to survive, grow, and reproduce. Trace elements: required by an organism in minute quantities. Electrons: form negative cloud and determine chemical behavior. Atomic mass: close to mass number but slightly number since it is the total mass of the atom. Isotopes differ from each other in neutron # and therefore mass. Unstable: give off particles and energy as radioactivity. Distribution of electrons determines chemical behavior of atom. Valence shell: outermost shell involved in bonding (gives atom its chemical properties) Chemical bonds: form when atoms interact and complete their valence shells.
