Two atoms of the same element contain the same number of protons. They can have different numbers of neutrons, but then they are isotopes of the element. If the number of electrons is different from the number of protons, they are ions of the element. read more

Atoms of the same element may have gained or lost electrons, making them different. Atoms of the same element may have different numbers of neutrons, giving them different atomic masses. These are called different isotopes of the element. read more

No. Two atoms of the same chemical element are typically not identical. First of all, there is a range of possible states that the electrons of an atom can occupy. Two atoms of the same element can be different if their electrons are in different states. read more
