Atomic weight minus number of protons.
The atomic weight minus the number of protons = the atom's neutrons.
Protons and neutrons= mass
the mass number of an atom is used to calculate the number of neutrons and protons in the nucleus of an atom
A typical atom of iodine contains 74 neutrons.
11 neutrons
45 neutrons
Atomic mass is simply the sum of the number of protons and the number of neutrons. If an atom has "A" protons and "B" neutrons, its atomic mass is A + B.
It depends it can be protons of neutrons depending on which atom but for many it is neutrons
There are 19 neutrons in a 36Cl atom.
52 neutrons.
35 neutrons
A typical atom of iodine contains 74 neutrons.
