₉₂U²³⁴ has 92 protons and 238 nucleons. It decays by emitting an alpha particle and becomes
Options
(a) ₉₂U²³⁴
(b) ₉₀Th²³⁴
(c) ₉₂U²³⁵
(d) ₉₃Np²³⁷
Correct Answer:
₉₀Th²³⁴
Explanation:
Emission of alpha particle, decreases the mass number by 4 and charge number by 2.
.·. Decrease in mass number = 238 – 4 = 234
Decrease in charge number = 92 – 2 = 90 ₉₀Th²³⁴ is emitted.
