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
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.
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.
