Number of neutrons = Mass number - Number of protons
The mass number of an atom is the number of protons plus the number of neutrons. This is is the same as the number of electrons plus the number of neutrons since the number of protons is the same as the number of electrons in an atom.
To find the number of neutrons in an atom you subtract the atomic mass fromthe mass number
The mass is the number of particles. Especially with atoms on the periodic table. The atomic mass is the number of proton and neutrons in the nucleus.
Yes, and in order to find the Number of Neutrons, subtract Atomic Mass from Number Of Protons, the result will be the Number of Neutrons for that atom *No. Of Neutron=Atomic Mass - Number Of Protons
The mass number of an isotope is the number of neutrons and protons in the isotope, let this be p +n = (mass number). To find the number of neutrons you need the atomic number (number of protons), let this be p. You then subtract the two: mass number - atomic number = no. of neutrons p + n - p = no. of neutrons = n
Neutrons, like protons are considered to have a mass of about 1. To find the number of neutrons, subtract the atomic number from the atomic mass.

Subtract the number of protons from the elemental mass number for the isotope of the element given to find the number of neutrons.
if you arent given the atomic numbert for an element - where could you find it?

Mass number = Number of protons + number of neutrons
false
You cannot, just by looking. The mass number is the number is the number of protons PLUS the number of neutrons -- but if you are not given the mass number, you have little to begin with except to look up the number of neutrons yourself. ---------------------------------------------------------------------- The other way to do it would be to measure the number of protons and neutrons in the laboratory. --------------------------------------------------------------------- Isn't it amazing about these people who say "there is no way of knowing" (as this answer formerly said), when the real answer is YOU CAN GO MEASURE IT ! That is the real way to find out nearly anything in chemistry and physics. D.A.W.
