Why mercury is liquid at room temperature pdf
4/08/2007 · Best Answer: Mercury’s valence (i.e. outer most) electrons are 2 electrons in the 6s “shell.” Because there are a pair, and the “shell” is full, mercury atoms don’t share electrons very well. This means that mercury atoms don’t bond to one another as well as other metals do.
Why is the element mercury liquid at room temperature? I’ve looked into this and it’s got something to do with the very weak mercury-mercury bonding, and that’s due to the fact that mercury atoms do not share their valence electrons readily. There are clues something odd is going on in the funny vapour pressure and surprising surface-tension, as it’s a liquid that’s not wet.
Mercury is the god of trickery, which enables him in his role as messenger of Zeus to fool you into thinking that he is capable of manifesting as both a liquid and a solid. If you pray to Mercury on his special day, which is Wednesday, when the sun is in either of his signs, Gemini or Virgo, he may give you the answer you seek.

Mercury is a liquid at room temperature because the “relativistic contraction” of its atomic orbitals makes it behave chemically almost like a noble gas, not wanting to share electrons with other atoms, even other mercury atoms! Note that mercury is monatomic in the gas phase, just like a noble gas. Of course this should not be pushed too far; mercury is not a noble gas. There are enough outer
Another classic case is why mercury is a liquid at room temperatures? The answer to that question (along with another, why is gold the colour it is?) is often anecdotally attributed to Einstein. More accurately, to his special theory of relativity.
Elemental mercury, a liquid at room temperature, is 13 times denser than water. Enough it turns out to support a man of average build and yes, if you type man sitting on mercury into Google, you’ll quickly find a 1972 photograph, published in National Geographic of a man suited and booted, sat unaided, albeit a little nervously, on top of a tank of rippling mercury.
