Document Summary

Mix of multiple choice, short answer, calculation. Everything up to friday, with the exception of one question on radioactivity (basic idea: matter and energy, matter = anything that occupies space and has mass, composed of atoms to then form molecules. The capacity to do work--the result of a force acting on a distance. Law of conservation of energy = energy is neither created nor destroyed: energy can be transferred or changed but cannot be created out of or vanish into nothing. Endothermic vs. exothermic: exo- = release energy into environment, endo- = absorb energy from environment. Specific orbit that is represented by n: use electron configuration to compactly specify the occupation of orbitals by electrons. Principal quantum number = n; specifies principal shell: higher the number, higher the energy. Subshell = s, p, d, f; specifies shape: s = spherical, p = dumbbell, d = clover, group number tells you how many valence electrons there are, periodic trends.
