The diagram below shows the model of an atom. Which object in the diagram has a negative charge?

30 protons, 65 neutrons, 35 electrons

30 protons, 30 neutrons, 35 electrons

30 protons, 35 neutrons, 30 neutrons

65 protons, 30 neutrons, 35 electrons

You must add the number of protons and electrons together to get the number of neutrons, 65.

You must subtract the mass number from the number of protons to get the number of neutrons, 35.

You must add the number of protons and electrons to get the number of neutrons, 30.

You must subtract the mass number from the number of electrons to get the number of neutrons, 65.

Part A: How many protons, neutrons, electrons are present in atom of zinc, Zn, with a mass number of 65? 

30 protons, 65 neutrons, 35 electrons

30 protons, 30 neutrons, 35 electrons

30 protons, 35 neutrons, 30 neutrons

65 protons, 30 neutrons, 35 electrons

Part B: Which of these accurately explains how to find the number of neutrons of zinc?

You must add the number of protons and electrons together to get the number of neutrons, 65.

You must subtract the mass number from the number of protons to get the number of neutrons, 35.

You must add the number of protons and electrons to get the number of neutrons, 30.

You must subtract the mass number from the number of electrons to get the number of neutrons, 65.
