There is no element with 28 protons in group 4. I think you are getting confused with group 4 and PERIOD 4. In period 4, the element with 28 protons is Nickel.
Each chemical element has a specific number of protons; the number of protons is equal to atomic number of the element.
The element that has half as many protons as zinc would be copper. Zinc has 30 protons, while copper has 29 protons. This means that copper has one less proton than zinc, making it the element with half as many protons.
The number of protons is the atomic number of the element.
neptunium has 93 protons.
Dubnium has 105 protons.
Nobelium has 102 protons.
