Neon, Helium, and argon
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.
There are six noble gases: helium, neon, argon, krypton, xenon and radon. All have completely filled outermost shell. Helium has 2 valence electrons while the other elements have 8 valence electrons.
Another name for noble gases is inert gases.
Elements of Group 18 may be called as;1-Noble gases 2-Rare gases 3- Inert gases
Helium, neon, and argon are the three lightest members of the noble gases.
Helium is least reactive element.It forms no compounds.Platinum is least reactive metal.
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. The first three noble gases (helium, neon and argon) have 1, 2 and 3 energy levels respectively.
Noble gases are also known as, 1- inert gases 2- rare gases 3- monoatomic gases 4- zero group elements.
There are six noble gases: helium, neon, argon, krypton, xenon and radon. All have completely filled outermost shell. Helium has 2 valence electrons while the other elements have 8 valence electrons.
Another name for noble gases is inert gases.
Metals, non-metals and noble gases.
Helium, Neon, Argon and if another Krypton.
Elements of Group 18 may be called as;1-Noble gases 2-Rare gases 3- Inert gases
Helium, neon, and argon are the three lightest members of the noble gases.
Chemical nitrogen 1 it is pure as it does not have any inert gases. 2 it is lighter compared to atmospheric nitrogen. 3 it is highly reactive. Atmospheric nitrogen 1 it has 1% inert gases. 2 it is heavier than chemical nitrogen due to the dust particles. 3 it is less reactive because of the inert gases.
it describes what are metals, non-metals and what are metalloids (semi-metals) group 1: Alkali Metals (reactive) group 2: Alkaline earth metals (reactive) group 3-12: transition metals group 13-17: non metals group 17: non metal, BUT ALSO a halogen group 18: Noble gases (inert - non reactive) Hope i helped you out, :) Alana
