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.

2. 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.
