If an atom of polonium-218 were to undergo alpha emission, followed by two beta emissions, which nuclide would result? lead-214 bismuth-214 polonium-214 lead-210

The resulting nuclide will be polonium-214.

Explanation:

Alpha decay: It is a process in which alpha particles is emitted when a heavier nucleus decays into lighter nuclei. The alpha particle released has a charge of +2 units.

The general alpha decay reaction is given as:

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

Atom of polonium-218 after alpha decay and two emissions:

1)

2)

3)

The resulting nuclide will be polonium-214.

the electrical  conductivity  of asolution  of an electrolyte is measured by determining the resistance of thesolution  between two flat or cylindrical electrodes separated by a fixed distance.
