NO. the first three noble gases (helium, neon and argon) have 1, 2 and 3 energy levels respectively.
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.
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.
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.
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
noble gases are least reactive
Generally, the least reactive elements are the noble gases.

Group 8. Commonly known as noble gases. Although it is true that the higher noble gases such as Neon and Helium are nonreactive, Krypton and Xenon can form compounds due to the high amounts of electron shielding experienced by its outer shell electrons. for example, Xe2Sb2F11
The coaxial cable I use has at least four layers, sometimes more. At a minimum it has to have a core, a layer of insulation, the second conductor and a coating of another insulator. Better cables have another layer of insulation around the second conductor, a layer of shielding and then the final outside coating.
Compared to what? But it would be less reactive because the s orbital is filled, the electrons are all paired. If you mean "Why is beryllium the least reactive of the Group II alkaline earth metals?", then this is because it has the least electron shielding, having an electron configuration of 2, 2. Beryllium is at the top as the first of the Group II alkaline earth metals, and reactivity increases as you go down Groups I and II.
the electron cloud is least dense where the probability of finding an electron is LOWEST
noble gases are least reactive
An electron.
The noble gases, they are Helium, Neon, Argon, Krypton, Xenon, Radon, and Ununoctinum.
The inner, or K shell, of the electron cloud has the least energy.
