I did this using one estimate for the number of aluminum atoms in 4.55 grams of aluminum, scaled it up to a kilogram, and divided aluminum's current price per kilo ($1.87 USD) by my estimate for the number of atoms in a kilogram of aluminum, yielding a price per atom of about $8.453*10^-26, or around eight sextillionths of a penny.
Of course, I'm only in ...

Strontium seems to be golden too, if of high purity. Look under "Eigenschaften". Beside that, also caesium seems to be of golden color.

Chloride will pit/rust 304 ,not quite as much rust/pits on 316/317. Many things make it worse such as limited air access ( under deposit or crevice corrosion ).Oxygen can help rebuild the passive film. For your long term exposure ceramics and glass containers is the best fix. For metal containers ,much higher alloy is needed such as Incoloy 825.

Current IUPAC recommendations suggest following electronegativity ordering. The symbol for iron (a less electronegative element among the two) should be written first: $\ce{FeCo}.$
From the section IR-4.4 Sequence of citation of symbols in formulae [1, pp. 58–59]:
IR-4.4.2 Ordering principles
IR-4.4.2.1 Electronegativity
If electronegativity is taken as the ...

I'm not an expert, but I think some metals boil directly into the plasma state, and that other metals (and most other gasses in general) start out as almost entirely unionized gasses when they boil and then slowly become more and more ionized as the temperature goes up. Thus, the difference between gas and plasma is more of a matter of degree than a first-...

Wikipedia gives several synthetic routes to zinc nitride. One of these routes is electrical discharge between zinc electrodes in a nitrogen atmosphere. Synthesis without electrical discharge generally uses ammonia as the ultimate nitrogen source.
