If a radioactive isotope undergoes beta emission,
a. The atomic number changes
B. the number of neutrons remains constant
c. The mass number changes
d. The todo isotope loses and electron
Molybdenum mainly undergoes beta decay. This decay process involves the emission of beta particles (electrons or positrons) from the nucleus, resulting in the transformation of a neutron into a proton.

Yttrium-90 (Z= 39, N=51) decays to Zirconium-90 (Z=40, N=50) by emission of a beta particle (Neutron - > Proton + beta minus). Zirconium-90 is stable.
Polonium-218 undergoes alpha decay to form lead-214, which then undergoes beta decay to form bismuth-214.
An isotope of phosphorus, phosphorus-32, undergoes beta minus decay as annoted by this equation: 32P => 32S + e- + ve The products are the sulfur isotope 32S, which is stable, and the beta minus partile (e-), which is a high energy electron, and an antineutrino (ve).
Mercury
Molybdenum mainly undergoes beta decay. This decay process involves the emission of beta particles (electrons or positrons) from the nucleus, resulting in the transformation of a neutron into a proton.
Naturally occurring scandium 45Sc is stable. However synthetic isotopes of scandium can have 36 to 60 nucleons. Isotopes with masses above the stable isotope decay through beta emission into isotopes of titanium. Isotopes below the stable variety decay, mainly by electron capture, into isotopes of calcium.
When 90Sr undergoes beta decay, it forms 90Y (Yttrium-90). In beta decay, a neutron is converted into a proton, and an electron (beta particle) and an antineutrino are emitted.
This isotope is lead-206.
Caesium-137 as it decays by beta emission.
Phosphorus-32 is the radioactive isotope that undergoes beta decay to produce sulfur-32. During beta decay, a neutron in the nucleus of phosphorus-32 is converted into a proton and an electron, resulting in the formation of sulfur-32.
Usually when isotopes undergo beta decay they emit an electron, but some isotopes emit a positron instead. This depends on the relative number of neutrons to protons in the isotope which type of beta particle is emitted. An excess of neutrons leads to the emission of an electron, while an excess of protons leads to the emission of a positron.
nothing, but another isotope with the same atomic mass is formed
SMD
Yttrium-90 (Z= 39, N=51) decays to Zirconium-90 (Z=40, N=50) by emission of a beta particle (Neutron - > Proton + beta minus). Zirconium-90 is stable.
During alpha emission, a radioisotope emits an alpha particle, which is composed of two protons and two neutrons. This reduces the atomic number of the parent isotope by 2 and the atomic mass by 4. The emission of an alpha particle transforms the parent isotope into a new element.
