What is a pseudo noble gas configuration? Electron Configuration The electron configuration of an atom shows the placement of electrons around the atom's nucleus. The outer most electrons reside in what is known as the valence shell. The electrons in the valence shell are responsible for the sha...
Sun-stuff, new, lazy, hidden, strange, gas-from-radium; helium, neon, argon, krypton, xenon, radon. These noble (meaning unreactive) gases are not on the whole particularly rare substances. Helium, in fact, is the second most common element in the Universe, after hydrogen, while the ...
Why is argon a noble gas? What are the physical and chemical properties of halogens? What are electron configurations and periodic properties? How many valence electrons do the noble gases possess? Why is hydrogen not a noble gas? What are three properties of nonmetals?
Usually, the heaviest noble gas is considered to be radon, but some sources cite xenon or element 118 as the answer. Here's why. Noble gas elementsare mostly inert, so they tend not to form compounds. So, the easiest way to find the answer to which noble gas is the heaviest or most...

1.Have you ever ridden on a balloon Many tourist spots offer balloon rides inorder for people to see the beauty of a place from above. A balloon contains anoble gas called helium(氦). Formerly, balloons contained hydrogenbut hydrogen is very flammable and erous when uncontrolled. Therefore, ...
My high radon test result from a weeklong test of my 1961 home in US EPA radon zone 1 Radon basics Radon is a noble gas on the far right side of theperiodic table of the elements. I’m sure you know them by heart: helium, neon, argon, krypton, xenon, radon, and now, apparently...
