Atoms of the same element must contain the same number of protons. This is because of the positive charge they provide.

of protons.
protons
No, atoms of the same element have the same number of protons. Atoms of the same element with different numbers of neutrons are called isotopes.
protons
Every atom categorised within the same periodic element should contain the same atomic number, which represents the number of protons within the nucleus. Each element is unique in how many protons reside in one atom, for example all oxygen atoms would contain eight protons and hydrogen atoms would only contain one proton.
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.
The number of protons in the nucleus of an atom determines an element's atomic number. In other words, each element has a unique number that identifies how many protons are in one atom of that element. For example, all hydrogen atoms, and only hydrogen atoms, contain one proton and have an atomic number of 1. All carbon atoms, and only carbon atoms, contain six protons and have an atomic number of 6. Oxygen atoms contain 8 protons and have an atomic number of 8. The atomic number of an element never changes, meaning that the number of protons in the nucleus of every atom in an element is always the same.

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.
All atoms with the same number of protons are atoms of the same element. The number of protons is the atomic number of the element.
Atoms of the same element that differ in the number of neutrons they contain are known as isotopes.

All atoms of the same element contain the same number of protons and electrons, but atoms of a given element may have different numbers of neutrons. Atoms with the same number of protons but different numbers of neutrons are called isotopes. An element has many isotopes--each with a close, but different number of neutrons.

1. An element contain only specific atoms of this element and no other atoms. 2. Compounds as calcium aluminates contain both aluminum and calcium.
A mole of any chemical element contain the same number of atoms - the number of Avogadro.
