okay boombastic ur right.

There is nothing got to do with it being heavier or abundant. They asked what makes it suitable for filament lamps.
Helium is also abundant if u guys don't know. It is used in weather balloons and in scuba diving(80%helium and 20%oxygen mixture, although oxygen is more abundant) .
 The reason why argon is  used in filament bulbs is because the metal filament will not burn in Argon and it reduces evaporation of the metal filament.

i know that they put inert gases because they are unreactive...there are many inert gases..so why did they choose argon..because its the easiest and cheapest gas to obtain...and they put helium in weather balloons just bcz its less dense than air
so y put an unreactive gas that is hard to obtain
it makes sense man

argon has the ability to reduce evaporation of the metal filament. U want to assume urs is right go on. I'm just telling the right reason

MY DEAR....
 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.

man all inert gases reduce evaporation of the metal filament not just argon

Argon is more efficient.

IGs whether u believe it or not...argon is used for other reasons than being abundant.

well i looked it up in chem. books and no book says that it has other functions than being unreactive
