    Answer:

    234 is the mass number of the resulting element that is uranium.

    Explanation:

    Beta-decay is nuclear process in which a neutron gets converted into a proton and an electron releasing a beta-particle. The beta particle released carries a charge of -1 units.

    [tex]_Z^Atextrm{X}rightarrow _{Z+1}^Atextrm{Y}+_{-1}^0beta[/tex]

    So, when protactinium-234 undergoes beta decay to form uranium-234 as resultant element.

    The reaction can be expressed as:

    [tex]_{91}^{234}textrm{Pa}rightarrow _{92}^{234}textrm{U}+_{-1}^0beta[/tex]

    234 is the mass number of the resulting element that is uranium.

    Answer is: mass number is 234.
    Beta decayisradioactive decayin which abeta rayand aneutrinoare emitted from anatomic nucleus.
    There aretwo types of beta decay: beta minusandbeta plus.In beta minus decay, neutron is converted to a proton and anelectronand anelectron antineutrino and in beta plus decay, a proton is converted to a neutron and positronand anelectron neutrino, so mass number does not change.
