Just the facts:

Sulfur Definition & Meaning - Merriam-Webster

 Yes, there's nothing like a good whiff of sulfur to cure your head cold and open up your sinuses.  

You shouldn't have any trouble recognizing the smell of sulfur, because it smells like rotten eggs.  

From either the Latin sulfur or sulphur, or from the Anglo-Norman French sulfre.  

Again an element with two spellings. Whenever I think of sulfur I also think of sulfuric acid  and the rhyme used in high school to remember its formula:

Silly Billy had a drink

But he will drink no more, 

For what he thought was H2O

Was H2SO4.

I doubt it. We all know you are too smart to drink sulfuric acid.

Sulfur is often associated with the underworld. Sulfur is the brimstone in preacher's fire and brimstone sermons warning of hell. 

It reeks to high heaven of rotten eggs in its most common compounds which are emitted by the metric tons during volcanic eruptions. Depending on the composition of the magma, an eruption often emits more gas than lava. Most of this is in the form of SO4 and H2S2. A key indicator that a dormant volcano is about to wake up is SO4 emissions.

The Taal volcano in the Philippines erupting in 2020. This highly active volcano constantly emits SO4. A surge in these emissions is a sure indicator it is up to shenanigans.

How could you think such a thing @Bill W. 🤣

To be honest the original had a different name but I though the rhyming name fitted better. Didn't even think of you in that context.
