23491pa undergoes beta decay. what is the mass number of the resulting element?

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.

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

The reaction can be expressed as:

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

nacl or sodium chloride is an ionic compound. this is because an ionic compound pertains to a compound that consists of positively and negatively charged ions. in this case, na (sodium) has a tendency to lose one electron when it reacts with with other atoms, so the resulting sodium ion contains 11 protons and 10 electrons, thus making it positively charged (na+), when chlorine reacts, it usually gains one electron to form an ion called chloride, thus making it negatively charged ( since the ions are oppositely charged, they attract.
