No. Not sure what you mean by a shielding layer- I would take this as the filled electron shells below the "outer", highest energy layer-- He has none, Neon has one , Argon has two.

Do all of the noble gases have at least 3 electron shielding layers?

No, not all noble gases have at least 3 electron shielding layers. The noble gas helium (He) has only two electron shielding layers, while the remaining noble gases (Neon, Argon, Krypton, Xenon, and Radon) have three or more electron shielding layers.


How many electron shielding layers do noble gasses have?

Noble gases have 8 electron shielding layers. This is because noble gases have a full outer electron shell, so they have filled all available energy levels up to the 8th shell, leading to 8 electron shielding layers.


Is it true All of the noble gases have at least three electron shielding layers?

No. He the lightest has only one 1s2. Neon is 1s2 2s2 2p6 so depending what you understand by the term layers - it either has two (complete shells) or three.


Do all of the noble gasses have at least two electron shielding layers?

No. If waht is meant are the layers below the outer layer then:- He has no shielding layer (electronic configuration 1s2) Neon has only one, electronic configuration 1s2, 2s2 2p6
