All atoms of any single element have the same atomic number in common. This is because the atomic number of an element is determined by the number of protons in the nucleus of its atoms. This number is unique to each element and defines the element. For example, all atoms of hydrogen have an atomic number of 1, all atoms of helium have an atomic number of 2, and so on.

While it's true that atoms of the same element generally have the same number of electrons, this can change if the atom becomes an ion (gains or loses electrons).

The atomic mass of an element is an average that takes into account the various isotopes of the element, so not all atoms of the same element will have the exact same atomic mass.

Lastly, while atoms of the same element do share similar properties, these can be affected by the atom's specific state (such as whether it's part of a molecule or a free atom).

So, the most accurate answer is A. They all have the same atomic number.
