What happens to the mass number and atomic number of a nucleus when it emits an alpha particle?: Mass number decreases by 4; atomic number decreases by 2.
What happens to the mass number and atomic number of a nucleus when it emits a beta-minus particle?: Mass number stays the same; atomic number increases by 1.
What happens to the mass number and atomic number of a nucleus when it emits a positron ( $\beta^+$ )?: Mass number stays the same; atomic number decreases by 1.
What happens to the mass number and atomic number of a nucleus when it emits a gamma ray?: Neither changes. The nucleus just rearranges and loses energy as gamma radiation.
What happens to the mass number and atomic number of a nucleus when it emits a neutron?: Mass number decreases by 1; atomic number stays the same.
