The number of protons, also called the atomic number.
Atomic mass minus the atomic number.
false
If you subtract the mass number by the atomic number you get the number of neutrons.
The number of neutrons in an atom is equal to the mass number minus the atomic number. The mass number is the total number of protons and neutrons in the nucleus, while the atomic number represents the number of protons. Therefore, the equation can be expressed as: Neutrons = Mass number - Atomic number.
The number of neutrons in an atom is equal to the mass number minus the atomic number. The mass number represents the total number of protons and neutrons in the nucleus, while the atomic number indicates the number of protons. Therefore, the formula can be expressed as: Neutrons = Mass Number - Atomic Number.
atomic mass number - protons = number or 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.
By subtracting the mass number and the atomic number, the number of neutrons can be calculated.
The number of neutrons in an atom can be found by subtracting the number of protons (which is the atomic number) from the mass number. The mass number is the sum of protons and neutrons in the nucleus of an atom.
Mass number minus atomic number = number of neutrons
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.
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.
