Question

A physics student, named Raman, is studying nuclear reactions. He found that ${}_{92}{U}^{238}$ nucleus changes to ${}_{91}{Pa}^{234}$ nucleus due to radioactive disintegration. Then the number of $\alpha$ and $\beta$ particles are emitted are __________ and __________ respectively.

• A. 1, 1
• B. 2, 2
• C. 1, 2
• D. 2, 1

Answer 1

The correct option is A 1, 1

${}_{91}{Pa}^{234}+{}_2{\alpha }^4{+}_{-1}^0\beta \to {}_{92}{U}^{238}$

So, $1\alpha and1\beta$ particles.
