Uranium 235 has 92 protons in its atoms. Calculate the number of neutrons in this atom

physics is pointless af and i don't know how to solve this pointless assignment

235 - 92

To calculate the number of neutrons in an atom, you need to know the atomic number (the number of protons) and the mass number (the total number of protons and neutrons in the nucleus).

In the case of Uranium-235, we know that it has 92 protons. The mass number of Uranium-235 is represented by the superscript, so it is 235.

To calculate the number of neutrons, you subtract the atomic number (protons) from the mass number.

Number of neutrons = Mass number - Atomic number
Number of neutrons = 235 - 92
Number of neutrons = 143

Hence, there are 143 neutrons in an atom of Uranium-235.
