You would subtract the atomic number from the mass number.
To find the number of neutrons in an atom you subtract the atomic mass fromthe mass number
the protrons, neutrons and electrons in a atom
Subtract the atomic number from the atomic mass after rounding each.
no, atoms don't have to have neutrons, neutrons are supposed to be neutral so it wont change the charge of the atom if you add or subtract neutrons from an atom. what will change is the mass number of the atom.
subtract. mass number - atomic number = number of electrons.
You would subtract the atomic number from the mass number.
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.
You subtract the atomic number from the atomic weight. For example, if you have a helium atom and its atomic weight is 4 and you subtract its atomic number (2) the number of neutrons in the helium atom is 2.
You subtract the atomic number from the atomic weight. For example, if you have a helium atom and its atomic weight is 4 and you subtract its atomic number (2) the number of neutrons in the helium atom is 2.
mass no - atomic no = number of neutrons in an atom.
Number of Neutrons = Mass Number - Atomic Number
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 atomic number from the atomic weight.
Subtract the number of protons from the mass number.
To find the number of neutrons in an atom you subtract the atomic mass fromthe mass number
the protrons, neutrons and electrons in a atom
subtract the atomic number by the Atomic Mass, and that is the answer. if its a neutral atom, there are probably the same number neutrons as protons.
