The number of protons in a nucleus is called the Atomic Number.
atomic no is the no of protones in a nucleus while atomic mass is the sum of protons and neutrons in nucleus of an atom....
depends on the proton number of the atom, for nitrogen it's 7 so there are 7. The mass number is the number of protons and neutrons so if you subtract the proton number you get the number of neutrons too
The atomic no of Plutonium is 94 so it has 94 protones and 239-94=145 neutrons in its nucleus.
the answer is that it is called a atomic number.
The number of protons in a nucleus is called the proton number, or atomic number. It is what defines which element we have.

6
the one with 81 as the smaller number.... if there isen't one, then you've got your calculations wrong...
a nucleus theoretically contains protones and neutrons but practically 33 different types of particles have discovered from nuclei of atoms , the modern research proved that the fundamental particles in nucleus are quarks and all other particles in nucleus are combination of 2 or 3 quarks the combination of 5 quarks is also possible.
Atomic number
the no. of protons or the no.of electrons inthe nucleus ofan atom is called the atomic number of that atom.
When the atomic number of one nucleus is the same with the mass number of another nucleus and the mass number the same with the atomic number of the second nucleus, then these two nuclei are called mirror.
