Chemical element mercury has the symbol Hg and atomic number 80 in the periodic table, a silvery liquid, its density (13.54 g / cm 3), freezes silver-colored slant of the blue looks like a bullet in his appearance and when (-38.9 ° C), and boil at (356.9 ° C) .
When the passage of an electric spark in mercury vapor, emits flashing dazzling, and ultraviolet light.
At a temperature (-269 ° C) becomes the mercury density - Note here that the degree of (-271 ° C is the degree of cumulus clouds heat left over from a cosmic explosion that launches microwave background radiation of the universe (CMB).
And thus become mercury (superior conductor) - the non-existent resistance to an electrical outlet; while the degree of absolute zero temperature is (-273.16 degrees Celsius), a temperature at which stop the movement of molecules.
The unusual character of the state of superconducting lies not only in the lack of resistance to electrical current, but also in the production of intense magnetic fields without the use of iron hearts of files, as electricity can be stored inside.
Isotopes of mercury
Mercury ten matches, seven of the stable, and unstable isotopes, and two equals produce negative beta rays, and one of these two isotopes and industrial isotopes are:
(80 bugs 196), a peer-existence in nature 0.1%, (80 bugs 198), a peer-existence in nature 10%, (80 bugs 199), (80 bugs 200), (80 bugs 201), (80 bugs 202), and (80 bug 204); all of stable isotopes in nature.
(80 bugs 197) isotope is unstable in nature, where turns into gold, as follows:
80 bugs> 79 y 197 +1 u 0
(80 bugs 203) isotope natural radiates rays negative beta, (80 bugs 205) peer-industrial radiates also rays negative beta; and the peer natural Cunha Silver tends to color gray dark, while peer industrial Venzirh tends to color red mercury oxide with being a means of Mittal.
Two types of radioactive mercury type is a Russian industrial radioactive isotope, and the type of Pharaonic Egyptian said about him, a kind of natural radioactive, but it is disconnected Kthavia very pure. Gram and up to $ 300,000 in it as he was talking about some naughty.
