The atomic number is really important for figuring out what elements are on the periodic table.
It tells us how many protons are in the center, or nucleus, of an atom.
Example: Take hydrogen, for example. Its atomic number is 1, so it has one proton.
Uniqueness: Each element has a different atomic number. This means no two elements share the same atomic number.
Now, let’s talk about atomic mass.
Atomic mass is like an average of an element's isotopes, which are different forms of the same element.
For example, carbon has an atomic mass of about 12.01. But its atomic number is still 6.
So, the atomic number helps us find and recognize elements very accurately!
