Document Summary
# of neutrons, although they have different masses, they do not differ greatly in chemical behavior; isotope avg mass a(%a) + mass b(%b);mass #=total # of protons & neutrons that make up nucleus of isotope; 1. : when emitted light shines through prism, separated into 4 colors of visible spect; >230 layers of concrete/steel, lead beta decay: neutron splits and kicks out e-. 2he sb: paper, glass, skin gamma decay: ray emitted to bring nucleus to lower energy state at same time as other decays, most dangerous sb: thick. 1e sb: steel plate, large bricks shield positron emission: Electron w/ quantum # l=1: in p-shaped orbital. During emission, electrons: lose energy, jump to lower level. Compounds form because overall system is: more stable, less energetic. # electrons in hg ion (hg^+2): 78 (nh4)2co3: ammonium carbonate.
