What are the differences between the atomic number and the mass number of an atom?
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....
How the protones of atoms are together in nucleus?
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
How many neutrons are in the nucleus of a Pu-239 isotope?
The atomic no of Plutonium is 94 so it has 94 protones and 239-94=145 neutrons in its nucleus.

What is the number of protons in the nucleus or the number the electrons in the energy levels called?
The number of protons in the nucleus is called the atomic number and is equal to the number of electrons in a neutral atom.
What element has 81 protones?
the one with 81 as the smaller number.... if there isen't one, then you've got your calculations wrong...

How many protones does carbon have?
6
Which does a nucleus of an atom contain?
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.
