In Class 9 Science (Structure of the Atom), atoms are classified based on their Atomic Number (Z) and Mass Number (A). The two most common classifications are Isotopes and Isobars. Let's understand the difference.
Isotopes: Same Atomic Number, Different Mass Number. (Belong to the same element).
Isobars: Different Atomic Number, Same Mass Number. (Belong to different elements).
Memory Trick: Iso'topes' = 'P' for same Protons. Iso'bars' = 'A' for same Atomic Mass.
Isotopes are atoms of the same element with the same atomic number but different mass numbers (like C-12 and C-14). Isobars are atoms of different elements with different atomic numbers but the same mass number (like Argon-40 and Calcium-40).
