Curium-247 has a half-life of about 15.5 million years. This allows us at least to know there have no supernova explosions too close to Earth recently, otherwise Cm would have been found in nature long ago. That half-life still doesn't come close to Pu-244 at 80.8 million years so Cm is indeed, essentially, more radioactive than Pu.

Caesium hydroxide is very alkaline anyway . . .

@qazmatron LOL wikipedia. GTFO

Look up "idiot's apostrophe" on Google.
A video is just one picture that happens to move, a "motion picture".
And this video isn't a video, it's an audio with a face. Audio is only a few hundred words.
Welcome to twitworld.

@qazmatron they say that a picture replace's a thousand word, a video is made up of (normally) 30 pictures per second, 67x30=2010, 2010 pictures are 2010000 words, fuck Wikipedia.

@qazmatron Lol, go to wikipedia

@bearpatch626 Yep. CsOH are used in some organic reactions. Usually when you need a strong source of OH but don't want any undesirable directing effects caused by smaller Na or K ions (Cs ions have no directing effects because the ion is too large).

any uses for alkaline cesium hydroxide ?

Curium powers the Spirit Rover.

This comment has received too many negative votes show
Uninformed.
Uninformative.
Incorrect. (It's 120 watts per GRAM for Cm-242.)
Not useful in audio format. (Talking head at a desk does not make it a video.)
(Some of their other videos are better.)
Viewers, go to Wikipedia and READ if you want to learn about elements.

@qazmatron oh you're not being very kind....
we put quick videos up on every element some time ago and are gradually updating all of them.... this is really more of a placeholder
but thanks for your warm words anyway! ;)
