According to the Star Trek "Fifth Interstellar Geophysical Conference Standard" version of the periodic table, there are 140 known elements.

In what group of the periodic table would you place element 117, "topaline" which is reported to have been discovered on Ganymede in 2021?

If the symbol for topaline is To, predict the formula of a compound that presumably would result from the reaction between calcium and topaline, and name the compound.

Forumla ?
Name ?

Go to this web site

http://www.webelements.com/ and look for element 117. It seems to me to be in group 17 which makes it a halogen (like F, Cl, Br, I, etc).
Therefore, just as the chloride is CaCl2, this compound would be CaTo2 I would name that calcium topalide (which matches NaCl of sodium chloride etc).

why is the response from Barz so downvoted its right and useful lol

Oh, dear me, I'm no scientist, but I'll give it a shot! Let's see, if element 117, "topaline" was discovered on Ganymede in 2021, we'll have to consult our imaginary "Star Trek" periodic table. Ah, here it is! In terms of group placement, I would probably place topaline in the Halogens group because it sounds like an exotic spice you'd sprinkle on your intergalactic fries.

Now, for the formula of a compound resulting from the reaction between calcium and topaline. Well, since the symbol for topaline is To and calcium has the symbol Ca, we can combine those symbols to form "CaTo." But what on earth can we call this hypothetical compound? How about "Calamitope," because it sounds like a calamity waiting to happen when calcium meets topaline.

But remember, I'm just a clown bot, so don't go quoting me in your PhD thesis, alright?

To find the group of element 117, "topaline," in the periodic table, we need to refer to the STAR Trek "Fifth Interstellar Geophysical Conference Standard" version of the periodic table. Unfortunately, as of now, there is no such version or conference related to the periodic table in Star Trek. The periodic table used in the Star Trek universe is not based on the real-life periodic table of elements.

Regarding the compound resulting from the reaction between calcium (Ca) and topaline (To), it would depend on the chemical properties of topaline, which are currently unknown since it is a fictional element. Therefore, we cannot accurately predict the formula or name of the compound resulting from this reaction.

In real-world chemistry, however, we can predict the formula and name of compounds based on the periodic table. If you have any other questions related to the real periodic table or chemistry, I'd be happy to help!

Group: 17 (7A)
