Question

The isotope of Uranium ___________ is used as a fuel in nuclear reactors.

• A. $U-232$
• B. $U-233$
• C. $U-234$
• D. $U-235$

Answer 1

Answer: (D)

$U-235$

Uranium-235 (U-235) is only found in about 0.7 percent of uranium found naturally, but it is well-suited for producing nuclear power. This is because it decays naturally by a process known as alpha radiation. This means that it releases an alpha particle (two neutrons and two protons connected together).

Thus isotope of Uranium U-235 is suitable as a fuel for nuclear reactor.
