Which four elements are named after planets?

Answer 1

The simple answer is Neptunium (Neptune), Uranium (Uranus), Plutonium (Pluto) and Tellurium (Earth). There is, however, a debate about two of those and one other so read on if you want:

The Debates:MercuryWas Mercury named after the planet or the Roman god? Well, the Romans most definitely named the planet after the god, but their name for what we call mercury had nothing to do with either. They called it hydrargyrum, which means "liquid silver," for obvious reasons. Later, alchemists related seven Roman gods to seven different metals for reasons not important to the debate. The god that was related to what they called "quicksilver" was Mercury. In no time period has the element actually been directly linked to the planet, rather both the planet and the element were named after the god. PlutoniumPluto is now considered a dwarf planet, not a planet, so can we still accurately say that it was named after a planet? Yes, we can. When it was discovered and named in 1941, Pluto was defined as a planet, therefore it was named after a planet. TelluriumIt is true that tellus is one of the Latin words for earth, but in what context? Does it mean:

"the planet third in order from the sun, having an equatorial diameter of 7926 mi. (12,755 km) and a polar diameter of 7900 mi. (12,714 km), a mean distance from the sun of 92.9 million mi. (149.6 million km), and a period of revolution of 365.26 days, and having one satellite."

or something more like:

"the loose soft material that makes up a large part of the surface of the ground and consists of disintegrated rock particles, mold, clay, etc; soil."

It turns out that the second definition of tellus was used by the Romans in everyday life, but it's actual meaning was "the Mother God" or the "God of the Earth" (akin to the Greek god Gaea). So was Tellurium named after the planet Earth, the soil, or the Roman god Tellus? Fortunately, the man who named it, Martin Heinrich Klaproth, can answer the question. In his paper announcing the new metal, he wrote that he derived it's name "...von der alten Mutter Erde Name entlehnten..." (Academy of Sciences of Berlin, 25 January 1798) which means, "...borrowed from the old name of Mother Earth..." So, Tellurium was named after the Roman god that protected the entirety of the Earth, not the planet Earth.

The argument, however is a bit more subtle than that. To the Romans, the planet Earth was the 2nd definition above. All of the other ways that we define a planet now were not known to the Romans then. Tellus, as with every other Roman god, was a personification of what she oversaw, not just a protector. To the Romans, she was the Earth, so I'll argue that the element was actually named after a planet.

Answer 2

The four elements named after planets are mercury (for Mercury), uranium (for Uranus), neptunium (for Neptune), and plutonium (for Pluto).

Answer 3

There are actually several elements that are named after planets. Five of these elements are plutonium, mercury, neptunium, uranium, and tellurium ('tellus' is Latin for 'earth').

Answer 4

Mercury is named after a planet. I'm 11 years old. Honest. I don't think there's any more. Hope I helped?
