Atomic Mass is simply the sum of the number of protons and the number of neutrons. If an atom has "A" protons and "B" neutrons, its atomic mass is A + B.

protons plus neutrons = atomic number


How can you calculate the number of neutrons N in an atom?

equal to number of protons


How do you calculate the number of neutrons an element has in its nucleus?

You need to find the atomic number, and the atomic mass. The atomic number i the number of PROTONS in the nucleus, the atomic mass, or mass number, is the number of PROTONS and NEUTRONS in the nucleus. To find the number of neutrons you subtract the atomic number from the mass number.


In order to calculate the number of neutrons you must subtract the from the?

Number of neutrons = Mass number - atomic number


How do you calculate how many neutrons there are in a atom?

The atomic weight minus the number of protons = the atom's neutrons.


What equation tells you how to calculate the number of neutrons in an atoms?

This equation is:Mass number - number of protons = number of neutronsMass number is the sum of protons and neutrons and has a value near the Atomic Mass of an isotope.


Can you use the atomic number and atomic mass to calculate the number of each subatomic particle?

atomic number = number of protons = number of electrons atomic mass = mass of protons + mass of neutrons

How do you calculate how many neutrons are in a atom?

Atomic weight minus number of protons.


How do you determine the number of protons electrons and neutrons present in an element by identifying its atomic and mass numbers from the periodic table?

Atomic number means number of protons present in an atom. Atomic number= number of protons. mass number = number of neutrons+ number of protons. So if you subtract the number of protons you get neutrons and if you subtract neutrons you get protons. mass number - protons= neutrons Mass number - neutrons = protons.


What does mass do?

The Atomic Mass is equal to the number of protons plus neutrons. So if you know the atomic number then you can find out the number of neutrons Atomic # is the amount of Protons or Electrons Atomic Mass- Number of protons plus neutrons Atomic Mass-Atomic Number = Amount of neutrons
