D
Uranium (U)
Verified step by step guidance1
Understand that the number of protons in an element is given by its atomic number, which is unique to each element and determines its position on the periodic table.
Identify the atomic numbers of the given elements: Lead (Pb), Gold (Au), Uranium (U), and Oganesson (Og). You can find these values on a periodic table.
Compare the atomic numbers of these elements to determine which one has the highest value, since the element with the largest atomic number has the most protons.
Recall that Oganesson (Og) is a synthetic element with a very high atomic number, typically listed as 118, which is higher than Lead (82), Gold (79), and Uranium (92).
Conclude that the element with the largest number of protons among the options is the one with the highest atomic number, which is Oganesson (Og).
