Nuclear decay that produces a daughter atom with the same mass number as the parent atom and an atomic number that is one more than the parent atom.

Answer 1

The type of nuclear decay described here is beta decay.

Answer 2

plus or minus

Answer 3

Beta decay can either be a beta minus (β-) decay, where a neutron in the nucleus turns into a proton, releasing an electron and an antineutrino, or a beta plus (β+) decay, where a proton in the nucleus turns into a neutron, releasing a positron and a neutrino.
