Wonders Of Helium

Introduction atomic heel 2 is the second to the highest degree abundant element in the universe, next to hydrogen. atomic number 2 is emblazonless, odorless, and tasteless. It has very low boiling point, and is ceaselessly monoatomic. atomic number 2 is very sm all in all and extremely light. It is the least excited of all elements; it does non react with any other elements or ions, which result in no helium-bearing minerals in nature. helium was first off notice by studying the Sun, and was named after the Greek name for Sun, Helios. undersurface helium conduct electrical energy? Helium rotter conduct electricity, but is not useful as a theater director. Like all noble gunslingeres it emits a tinge in the visible wavelengths when put in a thermionic valve at low pressure and subjected to a high current. This is called northeast light, for any of the noble gases, whether or not neon is included. why is helium a poor conductor of electricity? Helium is not a unspoiled conductor of electricity since its valency band is fully and there is a large cattle farm between this and its conduction band which means that electrons cannot be pay away promoted from the Fermi (a unit of length, 10?15 m, use in measuring nuclear distances) level to the conduction band...hence electrons argon not free to bear on and there is no conduction. push aside helium conduct stir up? Helium is a good heat conductor. Why is helium a good heat conductor?

Its low atomic mass, thermal conductivity, particular heat, and sound revive are the greatest after hydrogen. collect to the sma ll sizing of helium atoms, the diffusion rat! e finished solids is three clock faster than air and 65% greater than hydrogen. The element is inert, monatomic in standard conditions, and least piddle soluble of the gases. personal effects of heat and cold on a amplify change with helium, and why these effects find: Helium is greatly affect by temperature. When helium is heated, it causes the molecules to move faster and with more energy, and the gas expands (if you fill a billow with helium and it is heated the balloon will expand and eventually...If you sine qua non to get a full essay, order it on our website: BestEssayCheap.com
