Question

how do you find the number of neutrons in an atom? it is also the atomic mass it is also the atomic number subtract the atomic number from the atomic mass add the atomic mass and the atomic number

Explanation:

To find the number of neutrons in an atom, we use the relationship between atomic mass (mass number, approximately equal to the sum of protons and neutrons) and atomic number (number of protons). The formula is \( \text{Number of neutrons} = \text{Atomic mass (mass number)} - \text{Atomic number} \). So we subtract the atomic number from the atomic mass.

Answer:

C. Subtract the atomic number from the atomic mass (assuming the orange option is labeled C; if the options are labeled as A: It is also the atomic mass, B: It is also the atomic number, C: Subtract the atomic number from the atomic mass, D: Add the atomic mass and the atomic number, then the answer is C. Subtract the atomic number from the atomic mass)
