Abeka Physics Chapters 1-2

what decay occurs when neutrons down quark changes into an up quark and forces the emission of an electron; also produces antineutrinos, and has a higher amount of energy

what decay can be easily blocked by a piece of paper; low amount of radiation, emitting an high energy particle of two protons and two neutrons

decay caused by protons and neutrons layered in positions of high energy due to interaction among their quarks, ready to release that energy as they collapse

atoms with a neutron to proton ration greater than 1:1

region of high likelihood for finding an electron as it travels around the nucleus; the path of an electron around the nucleus

what occurs when a poistron and electron collide and convert their combined masses into a form of energy (usually gamma radiation); occurs anytime any particle collides with its corresponding antiparticle

what are the electron and positron considered because they have the same characteristics, but opposite charges?

postively charged electron

what equation was the start of modern physics
