Question

Number of neurons = (mass number)- _______)​

Answer 1

Answer:

TO FIND NEUTRONS NUMBER WE HAVE TO SUBTRACT MASS NUMBER TO ATOMIC NUMBER

Answer 2

Answer:

Number of neutrons = mass number - number of protons/electrons(in 0 oxidation state).

Explanation:

Since, the mass number is the sum of no. of neutrons and protons, hence no. of neutrons can be calculated by subtracting the no. of protons from the mass number of an electron.

Also, in zero oxidation state, (because the atom is electrically neutral) no. of protons are equal to the number of electrons. So, subtracting no. of electrons instead of protons makes no difference.
