1st QST.....answer is UNPOLARIZED

2nd QST......answer is n=2........bin dat L is the second energy level!

kenshin17: state d 3 ways thru which radiation can b detected?

Ways radiation particles are detected as listed below

1)Scintillation counter
2)Cloud Chamber
3)Geiger-muller counters
4)spinthariscope

Kunlexic: screening effect of d nucleous on the electrons

This answer of your does not satisfy me....Have you forgotten that it is still same electrons causing the SHIELDING EFFECT.My next question to burrow into you..would be

What are the reason the electrons causing the shielding effect not falling into the nucleus?
