What noble gases are related to nobles?
none
Is inert gases and nobles gases the same?
Good guess, poor grammar.
What does the term count rate mean when using a geiger counter?
A geiger counter measures ionizing radiation - alpha, beta and gamma (though gamma is indirect). The detector within a geiger counter is a Geiger Muller tube, it is basically a metallic gas-filled chamber with a thin wire anode running axially in the center of the tube and a cathode, the tube wall. The gas is most commonly an inert gas like the noble gases (like argon, neon). The anode is set to a very high charge compared to the tube wall. Also one end of the tube is typically has a thin mica wall or a thin glass wall to allow beta or alpha particles in. Once an alpha or beta particle enters the tube they can collide with the gas atoms forming an electron and postively charge ion. The electron speeds off to the positively charged anode while the ion accelerates to the cathode. Along the way the electron or ion can collide into other gas atoms creating more free electrons and ions and they in turn can knock other gas atoms creating an avalanche effect. The surge of electrons on the anode causes a current pulse that can be measured as a hit by a counter. In the presence of radiation sources the geiger counter's hits per second will increase significantly. As a side note gamma radiation first has to knock an electron from the side wall and it is this electron that causes the cascade.
Why are nobles gases special?
Noble Gases have an 'octet' which is a completely filled outer energy level with 8 electrons, except for Helium which has 2 valence electrons. This makes these gases in group 18 very stable.
Are Noble gases most reactive element on the periodic table?
No. They are the least because their energy levels are full.
What is chemical quenching?
Color quenching is the attenuation of photons produced by a scintilator due to absorption and scattering. This effect, combined with the chemical quenching (attenuation of the transfer of energy from the solvent to the scintillator gives the total quenching effect of the scintillator/solvent mix.
What are two important properties of the gas used in the chamber of a Geiger counter?
The gases are typically inert gases and halogens. They are easily ionized and are maintained at a low pressure inside the chamber. (This avoids detecting a large number of high energy photons from ionizing radiation.)
What noble gases are related to nobles?
none
Is inert gases and nobles gases the same?
Good guess, poor grammar.
Why are the nobles gases nonreactive?
They are already balanced. They have a full outer shell.

What does the term noble mean when referring to nobles metal And noble gases?
less reactive
What are nobles gas?
The nobles gases are the elements located on the very right of the periodic table. The elements are Helium, Neon, Argon, Krypton, Xenon and Radon. The common thing with the noble gases is that they have full outer shells, and don't react with any elements.
What kind of gas lights up lights bulbs into various colors?
Nobles gases like argon, neon....
Why are nobles gases special?
Noble Gases have an 'octet' which is a completely filled outer energy level with 8 electrons, except for Helium which has 2 valence electrons. This makes these gases in group 18 very stable.
What is the importance of nobles?
noble gases are of very importance in our daily life as we make conclusions about the other valence shell completion of other elements by knowing the noble gases valence electronic configuration
What do nobles gases have?
All noble gases have completely filled valence orbitals. Heleium has 2 valence electrons whereas the rest have eight. They have stable electronic configuration and are hence chemically inert at room temperature.
