Mercury (Hg), Uranium (U), Neptunium (Np), and Plutonium (Pu) are the four elements in the periodic table that are named after planets. Mercury is named after the planet Mercury, Uranium after Uranus, Neptunium after Neptune, and Plutonium after Pluto (although Pluto is now classified as a dwarf planet). It's worth noting that the names of these elements were inspired by the planets and their corresponding Roman gods, reflecting the influence of astronomy and mythology on the naming of chemical elements.
