Isotope

Real World Example

Imagine you're trying to find your friend in a crowd, but they keep changing their outfit. This situation is similar to trying to identify isotopes of the same element, where each isotope has a different number of neutrons, much like your friend changing outfits. Just as your friend remains the same person despite changing clothes, an element remains the same element even though its isotopes have different neutron counts; the difference in clothing is like the difference in neutron numbers.
