# How Many Neutrons are There Atoms ?

How many neutrons are there in _{92}U^{238} atoms ?

- 92
- 238
- 146
- 330

**Answer: (3) 146**Explanation:-

_{92}U^{238 where, Atomic number = 92 and Atomic weight = 238}

^{Number of neutrons = Atomic weight – Atomic number = 238 – 92 = 146 Hence, the number of neutrons is 146}
