Different number of neutrons result in different isotopes:
- Hydrogen - 1 proton, no neutrons
- Deuterium - 1 proton, 1 neutron
- Tritium - 1 proton, 2 neutrons (radioactive)
Different oxidation states by exchanging electrons between higher energy "hidden" orbitals and valence orbitals:
- Ferrous - Iron with 2 electrons in valence orbitals
- Ferric - Iron with 3 electrons in valence orbitals

What is the unchanged element of isotopes?
"element" is a very confusing word for what you are asking. But what I think you are asking is what part of an atom does not change with an isotope. I'll answer that question. An isotope of an atom is a variation fo the element in which the atom has a different number of neutrons. However, the number of protons can never change in a single element. So no matter how many atoms of a certain element are gathered, no matter how many different isotopes there are, they all have the exact same number of protons.
How many protons does Kr-83 have?
An element's atomic number gives its number of protons. Krypton's atomic number is 36. Thus it has 36 protons, regardless of the isotope.
What number never changes in a neutral atom?
The number of protons in the nucleus never changes in a neutral atom. This is because the number of protons determines the element's identity.
What is the difference between atomic mass number and atomic number?
Atomic mass number is the average atomic mass for that element, which is : All the isotopes' masses known for that element averaged up. Atomic number is the element's "identity", the number of protons the element and all its isotopes have. All the isotopes of a given element will have different number of electrons and neutrons, but the protons of the element never will change.
Does the mass number and the isotopes distinguish an element from a different one?
Well your question is not exactly clear. But the ONLY thing that defines one element from another is the number of protons it has. Hydrogen has 1 proton, helium has 2 protons and so on. A neutral atom has an equal amount of protons and neutrons. An isotope is an atom that has an imbalace of of protons and neutrons, but only the number of neutrons can change. Never protons, because that would make it another element. Protons and neutrons each wiegh 1amu (atomic mass unit). A neutral helium atom has 2 protons and 2 neutrons. So its atomic weight is pretty much 4amu. Electrons wiegh 1836 times less than 1amu so they are almost signifigant to the mass of an atom. Number of protons make an element what it is.
What part of the atom has to stay the same for it to be the same element?
The sugar and phosphate group of nucleotides never change. There are four possible nitrogenous bases and thus it is the only part of nucleotides that can change.
Can the atomic number change over time?
No. The atomic number of an element never changes. It is the number of protons and it defines the element. In certain types of radioactive decay, the number of protons can change, but then it is no longer the same (parent) element, but rather is a new (daughter) element.
The number of protons in an atom of an element will never?
For stable isotopes, those which are not radioactive, the number of protons remains constant. The number of protons is NEVER affected by a chemical reaction. (Alchemist s sort of hoped a chemical change could change one elemnt into another¬!) An element is defined by its atomic number which is the number of protons in the nucleus. ... be greater or smaller than the atom's Atomic Number.
Is it possible to have carbon atoms with different numbers of protons?
No because the number of protons never changes or else the element changes.
Why would sodium never have 12 protons?
Sodium has an atomic number of 11, which indicates the number of protons in its nucleus. Thus, sodium would never have 12 protons since that would change its identity to argon, which has an atomic number of 18.
What detemines the identit of an element?
The number of protons it has in the nucleus. Number of electrons and neutrons can vary but if the number of protons changes, you have a different element. Number of protons is a constant in an element which never changes.
The part of an element that never changes is the?
The number of protons.

What type of ion forms when an atom loses protons?
Atoms NEVER lose protons, just electrons.
Does the number of protons in mercury ever change?
No it NEVER EVER EVER EVER changes other wise it would be a completely different element like aluminum .
