WAS THE ANSWER ~!

wat did u write???

i wrote that it has one more shell, cuz argon is in group eight having 18 protons and the next one has 19 nd its a metal in group 1 so it has one more shell containing one electron..
but i am not sure
IGs:
the only reason they put argon is bcz its unreactive
check ur chem books guys..its written there
so there is no difference between helium and argon they r both unreactive...so the reason is according to logic using a gas which is more abundant is much easier and cheaper..pure logic

The inert gas can be argon, krypton, or xenon. If the manufacturer wants to go cheap, argon is used. For a little better performance with an only slightly higher cost, krypton is used and this is common. For slightly better performance than krypton, xenon is used.

the fact mention above is da perfect one...
i told u 4rm my very.own ch.book!!!!!
they DIDNT ASKED GENERALLY.....THEY ASKED WITH RESPECT OT DA QUESTION ABT LAMPS!!!!!
Y DONT U GET IT?????? :(
nzpd9:
both helium and argon are unreactive..but theres 0.933% argon
and like 0.0005% helium in the air.
so argon is more abundant in air making it more efficient and easier to use in light bulbs than helium.
