The radioactive decay of uranium into thorium is represented by the equation ${}_{92}^{238}U \to {}_{90}^{234}{Th} + X$ . The unknown species $X$ is

Answer:

Solution:

The mass number of $X$ must be $238 - 234 = 4$ and atomic number of $X$ must be $92 - 90 = 2$ .

Hence, $X$ must be an alpha particle.
