Question
Let's examine an alpha emission reaction. Which of the following statements about this event is not correct? Choose one answer. a. In an alpha decay reaction, a particle gets ejected by the nucleus of the parent, yielding a daughter and another particle. b. The He atom hypothetically gets its two electrons from Th, assuming that initially the 238 92 U changes to 234 90 Th. c. There is a mass difference of 4 between the two elements and a charge difference of 4 between the two elements. d. The best way to remember an alpha decay reaction is that 4 2 He is the biggest, single, most identifiable particle that comes from the nucleus.Explanation / Answer
The statement c is incorrect.
The correct statement is, " There is a mass differemce of 4 between the two elements and charge difference of 2 between the two elements."
This is because, the mass of an a;pha particle is 4 units and the charge of alpha particles is 2 units.
