How many neutrons are in the nucleus of an atom that has an atomic mass of 36 and an atomic number of 25?

Neutrons = 11

Explanation:

To get the number of neurons an element has you have to subtract the number of protons from the atomic mass of that element.

The number of protons is equal to the atomic number of that element.

Atomic number = Number of Protons

So the number of protons is 25

Neutrons = Atomic mass - Number of Protons

Neutrons = 36 - 25

Neutrons = 11

11

Explanation: To calculate the number of neutrons in the core of an atom, we need to subtract the atomic mass from the atomic number. In this problem, we are given our atomic mass which is 36 and our atomic number is 25.

36 - 25 = 11

Therefore, there are 11 neutrons in the core of the atom.
