There seems to be a misunderstanding. Atomic numbers don't have a specific value like 30.

Atomic number refers to the number of protons in an atom's nucleus. It's a fundamental property of an element that determines its identity.

For example:

* Hydrogen has an atomic number of 1 because it has 1 proton.

* Oxygen has an atomic number of 8 because it has 8 protons.

* Zinc has an atomic number of 30 because it has 30 protons.

So, the statement "atomic number 30" is actually referring to the element zinc.

Let me know if you have any other questions about atomic numbers or elements!
