What are Isotopes?
Same Element: They share the same chemical identity.
Same Number of Protons: They have the same Atomic Number
Different Number of Neutrons: This is the key difference that changes their Mass Number.

A (Mass Number): Think of it as the 'Total Weight' (Protons + Neutrons).
Z (Atomic Number): The identity of the element (Number of Protons).
The Secret Sauce: Just subtract Top - Bottom (A−Z) to find the number of Neutrons
