I may not be very nice if you hold me,
But I could tell you the time.
My melting point is rather low for a metal;
Only mercury has one lower than mine.
Expose me to water and very angry I'll be,
Though some of my friends would be angrier than I.

vg674 May 31, 2008	Hm. I was think sodium, but I knew that couldn't be right. Good to learn something new!
drat Jun 09, 2008	doesnt sodium do the same? or similar? I recall touching it....once. excellent
tangled_brain Jun 09, 2008	Sodium is very similar! The things that distinguish Cesium from Sodium in this teaser are their meltings points, reactivity, and the fact that Cs is used to register time in official government atomic clocks.
unklemyke Aug 19, 2008	If you attempted tohold a handful of Cs, the reaction would cause youto cesium and desistium! Good Teaser!
benjam Sep 17, 2008	Bad rhyme lol
Dishhead5 Oct 27, 2008	I WAS THINKING TEH DEADLY FRANCIUM But Cs works too
precious1026 Dec 13, 2008	If the metal has such a low reactionary rating, then at what point is anger (fury) so prominent? I thought the level of reaction displayed the furious nature of the element or anger level? Excellent Teaser, Good to learn something.
tangled_brain Dec 13, 2008	oh, no, it is low in the group in the periodic table--Cs is actually very reacive.
tangled_brain Dec 13, 2008	Oh and thanks.
Battery Jan 21, 2009	Thought it was rubidium because you say "some of my friendS" which I thought ruled out Cs and Fr. I think Fr has a lower boiling point than Cs as well
princess2007 Mar 08, 2011	Yay!! I got that!
wolvesstar97 Oct 02, 2011	Small factual error: You have stated Lithium as being the most reactive of the alkali metals, but the intensity of the reaction goes UP along with the atomic number. So lithium is the leastt reactive.
Candi7 Jun 10, 2012	When I heard the part about the low melting point, I thought, Mercury! But then I read that it wasn't mercury and I was, like, oh.
