The statement that best describes the difference between these two atoms is:
**Atom Y is a different element than Atom X.**
Atom X, which has 7 protons, is nitrogen, while Atom Y, with 8 protons, is oxygen. Elements are defined by the number of protons in their nuclei. Thus, the differing number of protons indicates that they are different elements.
