Verified step by step guidance1
Understand that the number of protons in the nucleus of an atom is called the atomic number, which uniquely identifies each element on the periodic table.
Recall that elements are arranged on the periodic table in order of increasing atomic number, starting from Hydrogen with 1 proton.
Identify the atomic numbers of the given elements: Hydrogen (1), Gold (79), Uranium (92), and Oganesson (118).
Compare these atomic numbers to determine which element has the greatest number of protons.
Conclude that the element with the highest atomic number, and therefore the greatest number of protons, is the correct answer.
