Name a Valid Element

Technically it does though. Tungsten is also called Wolfram

It wasn't actually named after the planet like Uranium, Neptunium, and Plutonium were, but it does share a name with a current planet.

Well, 4 of the 5 are named after the same town of Ytterby.

Holmium is named after Stockholm.

Gold is gold

Also Vanadium...

Nah, it doesn't work like that. It's like if you and your cousin were both named after the same one of your mutual grandparents. It wouldn't then be accurate to say that you were named after your cousin.

Radon: Short for "radium emanation." It was discovered as a radioactive gas given off when radium decays.

Molybdenum: Means "lead-like," from the Greek molybdos, meaning "lead," because it's very similar to a common type of lead ore.

Platinum: From the Spanish platina, meaning "little silver," because it was first discovered (by Europeans, anyway) in a silver mine.

Protactinium: Originally called "protoactinium," meaning "before actinium," because it was discovered as the stage of uranium-235 decay right before actinium (uranium-235 decays into thorium-231, which decays into protactinium-231, which decays into actinium-227.)

The clue clearly says current planet, which I think is a giveaway that they are not including Plutonium.

They're both named after the Roman god.

Yes, but the element was named after the god, not the planet.

It is, but the element wasn't named after the planet.

Some would argue that Mercury isn’t a god either…

Nope, it's named after the god.

I wanted to say Palladium too, but I looked it up and apparently, it was named after some asteroid, not the goddes. The asteroid of course was named after the goddes, but the author doesn't count those. For the same reason, he doesn't count Mercury, because it wasn't named after the planet.

Good info, nice one - I tried copernicium as well. However, it was named after a person, not directly after a substance, so I agree that copernicium shouldn't count.

no

it can be a vowel or a consonant.

Pretty sure they’ve dealt with this already

Because in many words it is used as an independent letter to make a vowel sound (as opposed to letters like h or w which only make a vowel sound when combined with a vowel, as in "oh" or "aw.") For instance, in the word "fly" it makes the "eye" sound of a long i, and i is definitely a vowel. In a word like "really," it makes the "ee" sound of a long e. And in "Yttrium" it makes the "ih" sound of a short i, so it's being used as a vowel there as well.

Of course, it doesn't always do this. The word "yellow," for instance, has it make a consonantal "yuh" sound. But if it can, on its own, make a vowel sound in certain words, should it not be considered a vowel in those words?

Hi! I'm a self-appointed "Y is sometimes a vowel" expert. In English, a letter is considered a vowel when it is part of the pronunciation of a vowel SOUND. In English, a vowel sound can be thought of as a sound that can be held for an indefinite amount of time with an open mouth, no build-up of pressure anywhere, and the tip of the tongue not touching anything. When you say "hug", you can draw out the "u" sound to be longer... "huuuuuuuuug" can be pronounced. You can draw out consonants like "n", but there the tongue touches the roof of the mouth. For "s", there is a build up of pressure. As for the "Y" in Yttrium being a vowel, it's pronounced like "it - reum". You can hold out the Y's sound indefinitely: "iiiiiiiiiiiiiiiiiit - reum". Y is actually a vowel more often than not. It is a vowel in "actually", for instance. It's only NOT a vowel in words like "you", "yolk", and "lightyear".

This has been addressed in the comments many, many times already. The element was named after the god, not the planet.
