6. why
are noble gases placed in sepciale column ?​

Answer 1

Answer:

This is your answer

This is because every column is its own separate group, each possessing similar (not the same) chemistry, all based on how many electrons are missing from the outermost (valence) 'shell' of electrons. ... With Noble gases, helium, neon, argon, xenon, and radon, the valence shell is already full.

Hope it helps.
