Question

(A) If an atom of uranium-238( U ) undergoes alpha decay, what daughter isotope is produced? (B) If this radioisotope from (A) then undergoes beta decay, what new daughter isotope is produced. Show your reasoning and be sure to identify the name of the daughter isotopes. Use the image to the periodic table below to identify the daughter isotopes

Answer 1

Th-234, Pa-234

Step-by-step explanation:

In alpha decay, 2 protons and 2 neutrons are lost. So U-238 would become Th-234.

In beta decay, one neutron is turned into a proton. So Th-234 would become Pa-234.
