Excellent video about Tantalum! Thank you!! I cannot wait to until the Tungsten video!!!

Working on it! Revising Carbon too.

I know nothing about the periodic table or the breakdown of elements and I was able to understand everything in this video. Great job and thank you!

Tantalum looks like it would make really good jewelry, again like niobium. And it's not poisonous!

And, it's relatively inexpensive...

Yikes! To put that boiling point of 5,458 degrees C to perspective: that is just below the temperature of the sun's surface (ignoring the sunspots) which I believe is 5,600 degrees C! However, I think tungsten might be one of the few elements that might actually survive being vaporized on the sun's surface!!!! BTW for those who didn't know: "observationally stable" simply means "theoretically shouldn't be stable but hasn't been observed to decay" as no one really mentions what "observationally stable" really means.

Tantalum 180m has a nuclear spin of 9 while Tantalum 180 has spin 1 and Hafnium 180 and Tungsten has spin 0 the only other isotope it could theoretically decay into is Lutetium 176 by alpha decay (and a couple of gamma rays at the same time). It's really hard to lose 8 units of spin at one go, so it may have a half life much longer that that minimum.

@@sydhenderson6753I'm aware that basically tantalum-180m "wants to" decay and/or de-excite but is having trouble achieving that due to requiring to lose many units of angular momentum in order to do so as a result of its high nuclear spin.

I believe there are longer half-lives. Bismuth 209, which we normally consider "stable" is listed having a half-life of 2.01x10^19 years. That beats the pants off of Tellurium!

At $1 a gram it’s the same price as silver. If you’re a silver stacker you should consider buying tantalum also for its use in electronics.

What's a "silver stacker"? Someone who invests in Silver? Ron

CAPACITORS!!!! those Ta caps do not dry. they are eternal, unlike normal electrolythics.

What does the m1 after 180 mean?

Michael, Basically, it points to an excited state of the nucleus, m1 being the lowest energy state for that isotope. Just as electrons can occupy lower and higher energy states, so to can the particles in the nucleus. The "m" stands for "metastable" since these are usually short-lived. However in the case of Tantalum-180m1 it lasts for more than 10^15 years (the longest for any nuclear excited state, by the way...) Good article at: www.thoughtco.com/nuclear-isomer-definition-4129399#:~:text=Metastable%20and%20Ground%20State%20Notation&text=The%20first%20metastable%20state%20is,178m2%20or%20178m272Hf). Ron
