Can the atomic mass of individual atoms of an element vary?
No, the atomic mass of individual atoms of an element does not vary. The atomic mass listed on the periodic table is an average value that takes into account the different isotopes (atoms with different numbers of neutrons) of the element and their abundance in nature. Individual atoms of the same element will have the same atomic mass.
Do all atoms have the same protons?
In respect to different elements, no they don't, in respect to like atoms of one particular element, yes they do. The electrons are the particles that vary from like atoms of the same element. When the electrons and protons are uneven within an atom, you have a radioactive element.
Can neutral atoms of the same element differ in neutrons?
They can vary in neutron count, which would also change the atomic mass.
Is it possible for atoms of the same element to have different chemical properties?
Atoms of the same element differ in the number of neutrons in their nuclei. All atoms of a given element have the same number of protons, of course. The number of protons in a nucleus determines which element the atom is. But the number of neutrons can vary, and these different "versions" of a given element are called isotopes of that element. See the related question, which is linked below.
When can atoms of the same element vary in the number of?
Neutrons in their nuclei.

What are three facts about elements?
Elements are the building blocks of matter. All atoms of the same element have the same atomic number. The mass number of atoms of the same element can vary.
Neutral atoms of the same element can differ in their number of what?
Neutrons. If the differ in electrons they are not neutral and if they differ in protons then they are no longer the same element as the number of protons determines the name of the element.

Distinguishes one element from another element?
Elements are defined by the number of protons contained in the nucleus of their atoms. The number of electrons (the same as protons in neutral atoms) determine an elements chemical interactios with other elements. The number of neutrons (which can vary) determines an element's mass and relative stability.
When can atoms of the same element vary in the number of?
Neutrons in their nuclei.
How can cobalt-59 and cobalt-60 be the same element but have different mass numbers?
They have different numbers of neutrons. An element is all of the atoms that have the same number of protons, but the the number of neutrons and electrons may vary.
What does the atomic number reference?
The atomic number of an element is given based on the number of protons in the nucleus of all the atoms of that particular element. This applies regardless of the number of neutrons or electrons in any atom of that element. Atoms are initially classified according to the number of protons in the nucleus of an atom, and this will identify which element the atom is. We know that the number of neutrons a given atom of any element can vary, and these will be classified as isotopes of that element. We also know that the number of electrons in any atom will vary, too. Atoms with a neutral charge will have the same number of electrons as protons, but the number of electrons can vary for a number of reasons. The number of protons, however will allow an investigator to identify an atom as being a particular element, and the atom will be further classified from there according to the number of neutrons and/or electrons it has.
Do protons of an element vary?
All atoms of the same element have the same number of protons. Atoms of different elements have different numbers of protons. The number of protons determines the element.
