How many neutrons in isotope?

Answer 1

It depends on what isotope you're talking about. To find the number of neutrons in a particular isotope, take the Atomic Mass and subtract the atomic number. For example, Na has a mass of roughly 23amu and 11 protons, so an Na-23 atom would have 12 neutrons.

Answer 2

The number of neutrons in an isotope can vary depending on the specific isotope. Neutrons are located in the nucleus of an atom and their number can be determined by subtracting the atomic number (number of protons) from the atomic mass (protons + neutrons).

Answer 3

The isotope number minus the atomic number of the element. (Total # of Neutrons and Protons) - (Total # of Protons) = # of Neutrons

Answer 4

See the link bellow - the table of isotopes.

Answer 5

Each isotope has a specific number of neutrons.
