Why is helium atomic number 2?
Helium's atomic number is 2 because it has 2 protons in its nucleus.
What characteristics of the atomic structure of helium make it so such less reactive the hydrogen?
Helium has completely filled orbitals and is stable whereas hydrogen has one valence electron and is reactive.
Is helium a reactive molecule?
No. Helium is not molecular it is monoatomic. Helium is unreactive and forms no compounds.
What is helium's most common diatomic bond?
None. Helium has completely filled orbitals it is stable and chemically inert (non-reactive). So, helium exists as mono atomic and not as a diatomic species.
Which is the most stable out of the two Oxygen or Helium?
Helium is more stable, because it has completely filled valence orbitals.
What is the difference between bonding and anti bonding molecular orbital?
Electrons in a bonding orbital have lower energy levels than the average energy of a valence electrons in the isolated atoms between which the orbital is formed. Antibonding orbitals do not meet this criterion, so that anitbonding orbitals can be stable only in conjunction with bonding orbitals, whereas bonding orbitals can be formed without any accompanying antibonding orbitals.The molecular orbitals which is formed by the addition of atomic orbitals is called bonding molecular orbitals.The molecular orbitals which is formed by the subtraction of atomic orbitals is called antibonding molecular orbitals.
Why helium exist in mono atomic state?
Helium has completely filled orbitals, is stable and is not reactive. Hence they exist as mono atomic
Why is helium atomic number 2?
Helium's atomic number is 2 because it has 2 protons in its nucleus.
Which of the following elements is stable neon or carbon or boron or fluorine?
All of them are "stable" elements in at least one isotope. The word "inert" is the term that applies to neon as it has completely filled atomic orbitals and obeys the octet rule.
When elements are stable?
Elements are stable when they have completely filled (or half filled) orbitals.
Why noble gases exist either in atomic form or in molecular form?
They have completely filled valence electrons, hence are stable, chemically inert. So they exist as mono atomic species and not as molecules
What characteristics of the atomic structure of helium make it so such less reactive the hydrogen?
Helium has completely filled orbitals and is stable whereas hydrogen has one valence electron and is reactive.
What make neon make stable?
Neon has completely filled orbitals. hence it is stable.
Is helium a reactive molecule?
No. Helium is not molecular it is monoatomic. Helium is unreactive and forms no compounds.
What is the basis for exceptions to the aufbau diagram?
some elements have unusual atomic orbitals
Difference between bonding and anti bonding molecular orbital?
Bonding molecular orbital Its energy is less than that of parent atomic orbital.It is more stable than the parent atomic orbital.In B.M.O, the probability of finding electrons is maximum.Contribution of B.M.O is maximum towards the shape of molecule.Anti-bondingmolecular orbital Its energy is greater than that of parent atomic orbital.It is less stable than the parent atomic orbital.In A.B.M.O, the probability of finding electrons is minimum.It does not contribute towards the shape of molecule.
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.
