Helium has a unique electron arrangement compared to other noble gases because it has only two electrons, filling its first energy level and forming a stable duet. In contrast, other noble gases, such as neon and argon, have full outer electron shells with eight electrons, following the octet rule. This difference in electron configuration contributes to helium's distinct properties, such as its smaller atomic size and lower reactivity compared to the heavier noble gases.
What else can I help you with?
What elements in the periodic table don't bond?
Noble gases, such as helium, neon, and argon, typically do not form bonds with other elements due to their stable electron configuration. They have a full outer electron shell, making them chemically inert.
Is helium a noble gas or a chemical?
Helium is a noble gas. It is part of the group of gases known as noble gases which have low reactivity due to their full outer electron shells.
Why is helium's position not justified in periodic table?
Helium has 2 valence electrons and it should theoretically be placed along with group 2 elements. But since helium has completely filled orbitals (as do the noble gases), it is placed along with the noble gases.
Name the elements with highest ionisation enthalpy?
The elements with the highest ionization enthalpy are helium, neon, and argon. These noble gases have full valence electron shells and are very stable, making it difficult to remove an electron from them.
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.
Why is helium stable with a different arrangement?
All noble gases have completely filled orbitals. Helium has two valence electrons and its s-orbital is full and is stable. Other noble gases have completely fill p-orbitals as the valence orbitals.
Which elements have the same electron arrangement as Argon Chlorine Sulfur or Potassium?
No element has the exact same election arrangement as another element. However ion can have the same election arrangement as another element. For example Chloride (Cl-) has the same configuration as Argon, and Potassium (I) (K+) also has the same configuration as argon.
Why does helium belongs to noble gases where infact it has 2 valence electron?
Because helium has completely filled valence orbitals similar to other noble gases.

What is special about the outer electron orbits of helium?
Helium has only two valence electrons. All other noble gases have 8 valence electrons.
What is the least reactive element?
The noble gases: Helium, neon, etc.
Why the helium is not included in noble gases group?
Helium is not included in the noble gases group because it does not exhibit the full range of characteristics typically associated with noble gases. While helium is chemically inert like noble gases, it has certain properties that set it apart, such as a lower boiling point and lack of electron shell completions like the other noble gases.
All noble gases except helium have this?
Helium has 2 valence electrons. All other noble gases have 8 valence electrons.
