Unit 2 Review Topics Week 5 1) Where are protons and electrons located in the atom? Size of the nucleus? Size of the atom? 2) number of protons, neutrons and electrons in any atom, isotope or ion. Special care for negative ions. Atomic number, mass number? 3) mass for elements considering “weighted” averages. Can you work one backwards? 4) Coulomb’s law. What is effect of charge and distance between ions 5) light as a way of interacting with atoms 6) know wavelength, frequency, speed, energy per photon and energy per mole of photons for any kind of electromagnetic energy 7) know the metric prefixes from giga to pico ( and their size e.g. kilo= 10 3 ) 8) know the rough energy of electromagnetic energy from gamma rays to radio/TV waves (which is higher or lower) 9) know what gamma rays to radio/TV waves do to materials ( e.g. IR causes vibrations, microwaves causes rotations) 10) line spectra (individual atoms) vs. full spectrum from heated objects 11) Bohr model to explain line spectra ( fixed energy (quantized energies) and circular
