Verified step by step guidance1
Understand that the atomic number of an element corresponds to the number of protons in its nucleus and determines its position on the periodic table.
Identify the atomic numbers of the given elements: Radon (Rn), Gold (Au), Uranium (U), and Oganesson (Og). You can find these values in a periodic table reference.
Compare the atomic numbers of these elements to determine which one has the highest value.
Recall that Oganesson (Og) is a synthetic element with a very high atomic number, typically higher than naturally occurring elements like Uranium (U).
Conclude that the element with the largest atomic number among the options is the one with the highest proton count, which is Oganesson (Og).
