Are two atoms of the same element identical? Please answer this and I will mark the best answer as the brainiest answer.

No

Explanation:

Are two atoms of the same element identical?

No they are not, for multiple reasons,

1) Heisenberg uncertainty principle: Electrons don't have a definite position, and direction of motion, at the same time. So we can only know of the two. Therefore the atoms are not identical in terms of the location or direction of motion at any fixed point in time.

2) Isotopes, while the number of protons in the nucleus determine the element, atoms of the same element can have different numbers of neutrons in their nuclei.

3) Electrons again, atoms can exist in energized states, therefore we may have a different number of electrons
