An atom of the element zinc has an atomic number of 30 and a mass number of 65. how many protons does an uncharged zinc atom have?

the element zinc has 30 protons

Explanation:

Atomic number is the sum of all the number of protons present in an element. And, mass number is the sum of total number of both protons and neutrons present in an element.

When an atom is neutral in nature then its number of protons is equal to its number of electrons.

Since, it is given that atomic number of zinc is 30 so, it means that number of protons will also be 30.

Thus, we can conclude that there are 30 protons in an uncharged zinc atom.
