Wonders Of Helium

Introduction atomic topic 2 is the second most(prenominal) 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 completely 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. atomic number 2 was first off detect by studying the Sun, and was named after the Greek name for Sun, Helios. quite a little helium conduct electrical energy? Helium stomach conduct electricity, but is not useful as a theater director. Like all noble gunslingeres it emits a likeness 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? Hel ium is not a corking conductor of electricity since its valence band is fully and there is a large spreadhead between this and its conduction band which means that electrons cannot be respectable away promoted from the Fermi (a unit of length, 10?15 m, employ in measuring nuclear distances) level to the conduction band...hence electrons be not free to journey and there is no conduction. washbowl helium conduct stir up? Helium is a good heat conductor. Why is helium a good heat conductor? Its low atomic mass, thermal conductivity, specialized heat, and sound revive are the greatest after hydrogen. ascribable to the small sizing of helium atoms, the diffusion rate by solids is three clock faster than air and 65% greater than hydrogen. The element is inert, monatomic in standard conditions, and least wet soluble of the gases. personal effects of heat and cold on a amplify change with helium, and why these effects break: Helium is greatly affect by te mperature. When helium is heated, it causes ! the molecules to move faster and with more energy, and the gas expands (if you fill a heave with helium and it is heated the balloon will expand and eventually...If you command to get a full essay, order it on our website: BestEssayCheap.com
