The number of protons, also called the atomic number.
Atomic mass minus the atomic number.
The number of neutrons can be calculated if the atomic number and mass number of an element is known. The number of neutrons = Mass number - atomic number.
atomic mass number - protons = number or neutrons
false
If you subtract the mass number by the atomic number you get the number of neutrons.
You subtract the atomic number from the mass number.
By subtracting the mass number and the atomic number, the number of neutrons can be calculated.
Mass number minus atomic number = number of neutrons
The average number of neutrons that a specific element has is equivilent to the element's atomic mass minus the that elements atomic number. For example Helium has 2 neutrons because its atomic mass (4) minus the atomic number (2) is 2.
The number of neutrons in the nucleus is not the answer its wrong trust me Mass number = neutrons + protons. Atomic number = protons. Trust yourself to work out the difference.
Number of Neutrons = Atomic mass minus Atomic Number. Neutrons = 18[Atomic Mass] - 8[Atomic Number] Neutrons = 10
The number of neutrons in the nucleus is not the answer its wrong trust me Mass number = neutrons + protons. Atomic number = protons. Trust yourself to work out the difference.
