|
|
three stability factors of nucleus
|
mass defect("extra" energy/nuclear binding energy), band of stability(protons:nuetrons), magic number (certain # of nucleons in a completed energy level
|
|
|
transmutation
|
when atomic # changes, altering the identity of the atom (one element to another kind)
|
|
|
nuclear reaction
|
reaction that stabilizes nucleus
|
|
|
radioactive decay
|
spontaneous disintegration of a nucleus into a slightly lighter/more stable nucleus, comes with particle/electromagnetic radiation
|
|
|
what happens during alpha emission
|
releases an alpha particle, and reduces the number of protons and neutrons
|
|
|
w h d beta particle emission
|
a neutron is converted into a proton and an electron and beta particle given off
|
|
|
w h d positron emission
|
a proton is converted to a neutron and a positron, positron is emitted
|
|
|
w h d electron capture
|
an inner orbit electron combines with a proton and makes a neutron
|

|
|
|
fission
|
when nucleus sets of a chain reaction, splitting nucleus into to or more smaller nuclei (creates an atomic bomb status reaction)
|
|
|
fusion
|
when two or more nuclei of small elements combine to form a heavier nucleus (hydrogen bomb)
|
