That was my wife's question this morning as I was trying to wipe the sleep out of my eyes and get my caffeine levels up to par. It's spring and she had been looking at plant fertilizer rates. "Dunno"

So, off to google while she was making a short stack of pancakes.
Potassium is from "potash", the practice of putting wood ashes in a container and leaching out the lye, potassium carbonate or hydroxide. OK remembered that but it didn't explain the K.

K comes from the latin for potassium "kalium"
which probably comes from the Arabic for potassium "qali"

If I had to guess.. al-qali ..alkali

So anyway K, potassium = Kalium

 :D 2 pots, country ham, flapjacks... that's it, missing the magic G.
I do enjoy the stories behind stuff.

I found out the rest of the story, she just had me proofread a post for the farmers market market;

K2O,P2O5 and N the three main fertilizer make up,if I remember from High School a lone lone time ago.

That's it, on fertilizer it is listed as percentages of N-P-K like 10-10-10 or 0-0-50

I remember plumbum... plumbing, etc what's the story on au?

I was looking up the difference between brass and bronze the other day after one of Brad's posts, brass is copper and zinc, bronze is copper and tin, sn, stannum, I squirreled off in another direction before figuring out who Stan was :D

Lead is:  pb  (from Latin: plumbum)

Gold is: Au (from Latin: aurum)

Silver is: Ag (from Latin: argentum)

My metal shop teacher had a little saying to tell the difference between the makeup of Brass and Bronze.  "One has zinc, the other copper.  Just remember you cannot have two Zs."  So Bronze must have Copper and Brass must have Zinc.

There are many kinds of brass.  Red, yellow, naval, etc.  Brass is an alloy of copper, tin, zinc, and lead. Naval brass has no zinc due to salt environment.   Bronze is just copper and tin.  I worked in a machine shop and yellow brass was my favorite.  It machines easy and clean.  Gary

Apparently plumbum or its root predates latin.  Lead comes from old Irish "luaide". A lead weight hanging from a string gives us the plumb bob and then plumb, vertical. The romans ran water in pipes of lead because it was easy to work, they also stored wine in it. I remember Benjamin Franklin wrote something about that, it was used to sweeten spoiled wine even in his time although he spoke out against it, he knew it as a poisonous metal. I'm not sure when we figured that out.

So is Naval Brass really Bronze?

The Romans made a sweetener, Lead Acetate, by boiling wine in lead containers. It was a common sweetener among the wealthy and it probably caused a lot of chronic lead poisoning.

My old chemistry handbook doesn't list anything called Naval Brass, but it does give the formula for "Naval Journal Bearing" -- 83% Cu, 14% Sn, 3.5% Pb. That's Copper, Tin, and Lead, so it's not really a Bronze.

I learned AU was Almost Unaffordable (Gold), AG was "Almost Gold (Silver or the next precious metal down).

Iron was Fe for Ferrum (tho women - Females - need more iron in their diets), Can't remember why Mercury is HG, but there was something like that for that.  (IIRC Heavy Something)

And oh yeah...  Tin is Sn.  As in Tin Snips.  :-)

OK, sorry for checking in late but I may be a minor king in periodic chart jokes.  How did your mother fix the rips  in your clothes?  She sodium them.  What does the doctor do to male patients?
