Potassium, K, had 19 protons, 20 protons, 19 electrons. What is the charge of the atom’s nucleus. HELP

+ 19

Explanation:

The following data were obtained from the question:

Proton = 19

Neutron = 20

Electron = 19

Charge on nucleus =.?

From a background understanding of the structure of an atom, the nucleus of an atom contains protons and neutrons with the proton being positively charged and the neutron is neutral while the electrons being negatively charged revolve around the nucleus.

From the above question, we understood that the potassium atom has 19 protons which are all positively charged. This simply means that the nucleus has a charge of + 19 since the neutrons are neutral.

it means there are 3 atoms of oxygen

it is the most commonly accepted one
