Not in large quantities. My grand mother is a nurse, one day I liked the way mercury looked so i broke the thermometer and start playing with the it. [xx(]
what I remember is that it did not blend back together. Why is that?

High surface tension. Can't you see that the man is actually sitting on mercury??? You can't possibly do that on water!

I didn't really examined the picture in detail :P, i would not have noticed it if u didn't have told me. tx ;)
can you explain how to calculate mercury's tension ,and compare it to water's tension.
I like math calculations.  ;D

Have a look at this starting from page 142.

Don't worry, it didn't do anything to you (I hope you didn't swallow it, right?  :)). But that amount of mercury could be dangerous if you let it in the pavement (or in any other place without being closed in a container) for a long time without opening the windows: its vapour tension generates dangerous concentrations of the vapour in air, with time.

Because the drops' surfaces became dirty and so the drops couldn't touch effectively.

it makes sense. free surface energy and energy bindings,, comes to be like covalent bonds between atoms, right?

Have to do with:

is that they are sharing n/2 bonds, just like semiconductors. For example a tetravalent (silicon) is bond with a boron (trivalent) to make a extrinsic molecule.

Sorry what? It is still not making sense. Did you read those links?

Well, you just get back to doing your homework and/or studying or TV or computer games etc... :):):)

I'm afraid at one stage people weren't quite so aware of the problems Mercury presents. I would say about 30 years ago it was common for children to push the balls of Mercury around in a tray as part of their science lesson.
One of my lecturers was ill for a month after topping up a manometer with Mercury. He was riding home on his motorbike and suddenly lost his balance. He couldn't stand up and had to crawl along the footpath and into a pay phone. He somehow managed to ring 999 for help. He had not been told that he should take precautions with Mercury at all.

Do you mean that he only opened the manometer? How much time was it left opened?
Some years ago I heated with a flame some grams of Hg with some grams of tin in a test tube to speed up the formation of amalgam (no hood!), for about 1 minute; in those conditions the Hg vapours concentration in air shouldn't have been so low. I knew it was dangerous but I only took the test tube with a hand at ~ 0.5 metres from me. I didn't experience anything strange.
