Thank you for sparking our interest in the element iridium.

Ouch... Ron

The Iridium satellites were called so because originally 77 of them were planned to orbit earth, like the 77 electrons in an Iridium atom.

Thanks for that! Great info. I wonder why they never made it to 77. Probably found it worked with what they had launched. Ron

Thank you for such a great presentation. learned so much! i Love those Platinum metals

Thanks Mr. Meisterama! Ron

My recent motorcycle trip took me past a chance to see the K-Pg boundary in Drumheller, Alberta and right through Sudbury, Ontario. I did not go see the K-Pg and did not even know about Science North, so obviously I should do it all over again the right way!

I fear that I already have too many of those charts! (I can make one up, but it won't match Theo Gray's format exactly...) Ron

It never occurred to me before, but the standard kilogram must have been pretty small in size, given the density of iridium and platinum. Someday, if we go mining asteroids, we may crash the price of iridium. It's fairly rare in meteorites, but positively common compared with the Earth's crust. Most of the little we have is in the Earth's core, like the elements surrounding it.

I can't imagine the cost of mining asteroids will make it any cheaper, however! Ron

@@ronhipschman Maybe so, especially since you have to refine everything else in the metal asteroid. Still, several companies are going for it. It looks to me like iridium is the rarest element in the the Earth's crust that isn't a noble gas or radioactive.

I think I've answered this inquiry already. I will NOT be getting to Fluorine anytime soon. Sorry. Thanks, Ron
