What subatomic particles determine the identity of an element?

Explanation:
An element is identified by the number of protons in its nucleus. This count sets the atomic number, and each element has a unique atomic number. If you added or removed protons, you would be talking about a different element, not just a different form of the same one. Electrons influence charge and how atoms bond, but they don’t determine which element it is. Neutrons change mass and give rise to isotopes of the same element, but they don’t change the element’s identity. Quarks sit inside protons and neutrons, explaining their internal structure, but they don’t define the element you’re looking at in chemistry. So the protons in the nucleus are the defining factor.
