How many protons and neutron does a nucleus have?

The number of protons an atom has depends on which element it is. Every element has a different number of protons. And within each element, there will be a different number of neutrons, creating isotopes.


What is the differences between isotope and element?

Regular elements contain regular neutron number and the same number of protons and neutrons. Isotopes have different neutron numbers than the original element, but the same number of protons and electrons.


What would happen if one were to add a few protons to a neutron star would it become some sort of highly concentrated element?

A neutron star already does contain a few stray protons and electrons, but that does not make it a new element. A true atomic nucleus is bound together by the strong nuclear force. A neutron star is held together by gravity and is composed of neutron degenerate matter.


If the proton is 11 and the neutron is 12 what is its element?

If there is 11 protons then that would be Na or Sodium.


What element do you get when nitrogen14 loses a neutron?

Isotopic Nitrogen: still 7 protons, N(13).


What is the smallest eletrically neutral particle of an element?

The smallest electrically neutral particle of an element is the neutron. Neutrons are subatomic particles found in the nucleus of an atom along with protons. They have no electric charge, unlike protons that are positively charged.


What element has one proton one electron and no neutrons?

Yes, every element of matter has a corresponding element of antimatter, and antimatter elements have nuclei consisting of antiprotons, not protons. It depends, however, on whether one considers antimatter elements to be elements or "anti-elements."


What is another term for neutron number?

In a neutral atom the protons and neutrons are equal; protons are determined by the element's atomic number. Therefore, the "neutron number" can refer to the atomic number- in a neutral atom only.


What element has 12 protons 13 neutrons and 15 nucleons?

nucleons equal for protons and neutron total. so it should be 25 neucleons.
