Question

How to fint the neutrons on an atom if the atomic number and the mass is given?

Answer 1

we know that mass no. = no. of neutrons + no. of protons (1)

also, no. of protons = atomic no. (2)

from (1) and (2)

mass no. = atomic no. + no. of neutons

so, no. of neutrons = mass no. - atomic no.

that's it!!!!!!!.......

have a nice day
