If the number of protons changes so does the element, as the number of protons defines the element.
By the numbers of protons
No. Isotopes exist because atoms with the same number of protons per nucleus can have differing numbers of neutrons per nucleus.
Isotopes have the same number of protons and electrons; the number of neutrons is different.
If two atoms are isotopes, it means they have the same number of protons but different numbers of neutrons. Thus, they have the same atomic numbers, but different atomic masses.
All atoms of an element contain the same number of electrons and protons but they can have different numbers of neutrons. Atoms with different numbers of neutrons are isotopes.
By the numbers of protons
The isotopes of an element have the same number of protons, but different numbers of neutrons.
These atoms are called isotopes.

Isotopes have the same number of protons and electrons; the number of neutrons is different.
No. Isotopes have the same atomic number, protons and electrons. They have different neutrons.

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.
There are 6 protons in carbon. The weights of the different isotopes are due to different numbers of neutrons.
