They are called as isotopes of the given element.
Two atoms with the same number of protons are not two elements but one element. If they have differing numbers of neutrons, however, they are said to be of different isotopes.
The answer you are looking for is "isotopes" HOWEVER, please note you CAN NOT HAVE 2 elements with the same number of PROTONS. This is because the number of protons DEFINES an element. Isotopes are the SAME element but with differing numbers of neutrons.
Isotopes of an element have the same number of protons but differing numbers of neutrons in the nucleus.

No. Isotopes exist because atoms with the same number of protons per nucleus can have differing numbers of neutrons per nucleus.
the total number of protons and neutrons in the nucleus.
No, it is just the other way around!All isotopes of one particular element have the same number of protons (specific for that element) but are differing in neutron number.Example:Uranium has 92 protons (same as atomic number),butisotope U(235) has 143 neutrons and 92 protons (143+92=235)andisotope U(238) has 146 neutrons and 92 protons (146+92=238).
Isotopes of an element have nuclei with the same number of protons (the same atomic number) but different numbers of neutrons Neutrons (:
In the neutral state, all atoms of the same element contain equal numbers of protons and electrons. However, most elements have atoms with different numbers of neutrons. These are called isotopes.
Isotopes. for example, a 35-Cl, 34-Cl, 36-Cl are all chlorines but with different neutrons, which would change their mass but not number of protons (what defines an element)
The nucleus is made up of protons and neutrons. Most of the elements with low atomic numbers are equally protons and neutrons. However, as elements get heavier they will have more neutrons than protons, and since each weigh the same amount (1 atomic mass unit) these nuclei will get most of their weight from the neutrons.
