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?

Question

30
35
65
95

Answer 1

An uncharged atom has the same number of protons as it does electrons. The atomic number of an element indicates the number of protons in its nucleus. For zinc, the atomic number is 30, which means an uncharged atom of zinc has 30 protons.

So, the answer is 30.
