Number of protons in an atom’s nucleus
Real World Example
Imagine you're at a large conference trying to find your friend among a sea of attendees. Similar to how each unique outfit or accessory helps you identify your friend, the atomic number of an element helps identify the element itself. Just as your friend's distinctive features or attire distinguish them from the crowd, the number of protons in an atom’s nucleus defines the element and distinguishes it from others.
