To find the number of neutrons in an atom you would subtract what?

You would subtract the atomic number from the mass number.


What do you get when you subtract mass number from atomic number?

mass #-atomic#=# of neutrons


What do you get when you subtract atomic number from atomic mass?

mass #-atomic#=# of neutrons


What do you have when you subtract the atomic no from atomic mass?

Atomic number is number of protons in an atom while atomic mass is the sum of protons and neutrons in an atom when you subtract you will get the number of neutrons in an atom.


The mass number minus the atomic number?

If you subtract the mass number by the atomic number you get the number of neutrons.


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

In order to calculate the number of neutrons, you subtract the atomic number (number of protons) from the atomic mass (rounded to the nearest whole number). Neutrons are important for stabilizing the atomic nucleus alongside protons.


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

You can calculate the number of neutrons in an atom by subtracting the number of protons (which is the atomic number) from the atomic mass of the atom. The atomic mass is the sum of the number of protons and neutrons in the atom.


How do you know the number of neutrons an atom has?

You can find the number of neutrons in an atom by subtracting the atomic number (number of protons) from the atomic mass number (rounded atomic weight). The atomic mass number represents the sum of protons and neutrons in the nucleus.


How do you find the number of nutrons in an atom?

To find the number of neutrons in an atom, subtract the atomic number (number of protons) from the atomic mass (rounded mass number). Neutrons are neutral particles found in the nucleus of an atom along with protons.


To determine the number of neutrons in an atom, what must be done?

To determine the number of neutrons in an atom, subtract the atomic number (number of protons) from the atomic mass number (rounded mass of the atom). Neutrons are particles found in the nucleus of an atom and carry no charge.


Why can you subtract the atomic number from the atomic mass and get the number of neutrons?

Not the atomic mass but the mass number (of course, these values are similar - not identical).The mass number is the sum between the number of protons and the number of neutrons. As a consequence:Number of neutrons for an isotope = Mass number - Number of protonsThe number of protons is equal to the atomic number.


How can you determaine the number of a neutrons an atom has from an ayom's mass number and its atomic number?

subtract. mass number - atomic number = number of electrons.
