What is the expansion for the chemical symbol of Tungsten?
Tungsten is a chemical element with the symbol W and atomic number 74. Tungsten is a rare metal found naturally on Earth almost exclusively as compounds with other elements.
Tungsten gets its W symbol from its German name Wolfram. Wolfram comes from Wolframite, which was one of the ores in which Tungsten was most found. The name Tungsten is actually Swedish and translates into "Heavy stone" in English.
Because it retains its strength at high temperatures and has a high melting point, elemental tungsten is used in many high-temperature applications, such as incandescent light bulb, cathode-ray tube & vacuum tube filaments, heating elements and rocket engine nozzles.

I did not understand what was meant by expansion for the chemical symbol. I got this correct because I taught Chemistry for 18years but I think the question is a strangely worded one. It may have been better if it asked for the origin word of the symbol of Tungsten.

Badly worded question from a clone!!

Good first question, but the word "expansion" seems not to be correct in this question.

Anne Patrick, or at least why its letter on the chart of the elements is W.

Mic Fenst, I thought so, too. It took looking at the options to realize that we were supposed to identify the full word.

Anne Patrick, I've never heard it mentioned as such, either.

Seen Wolfram written on light globes, so took a punt on that.

Denise Currie,
Ridhi is another Quizzclub Clone. Ridhi joined in December of 2021 and hasn't answered a single question! You are complimenting Quizzclub. That explains why it was so oddly phrased. The administration is Russia-based and English is a second language.

So anyone else mentally adding "& Hart" to Wolfram? Just finished a "Buffy/Angel" marathon.
