Question

How many neutrons are in an atom of uranium-235 (²³⁵U) with atomic number 92?
Options
A 92
B 143
Correct Answer
C 235
D 327
Correct Answer

Option B is the correct answer.

Detailed Explanation

The number of neutrons in an atom is calculated by subtracting the atomic number from the mass number. For uranium-235, mass number = 235 and atomic number = 92. Number of neutrons = 235 - 92 = 143.

Hint

Neutrons = mass number - atomic number.
