Discussion Overview

The discussion centers on the presence of a nodal surface in the 2s subshell of hydrogen-like atoms. Participants explore the reasons behind the existence of nodal surfaces, the implications of wavefunctions, and the behavior of electrons in relation to the nucleus.

Discussion Character

  • Exploratory
  • Conceptual clarification
  • Debate/contested

Main Points Raised

  • One participant questions the reason for the existence of a nodal surface in the 2s subshell, seeking an explanation beyond the number of nodal surfaces.
  • Another participant asserts that all orbitals with the same main quantum number n have n-1 nodal surfaces, implying a general rule for hydrogen-like atoms.
  • One contribution suggests that energy increases with the complexity of the wavefunction, which correlates with the number of nodes present.
  • A later reply presents a more complex reasoning involving the balance of charges in an atom, the attraction of electrons to the nucleus, and the concept of electrons being confined to certain regions, leading to the existence of nodal surfaces where the wavefunction is zero.
  • This participant expresses uncertainty about the validity of their reasoning, indicating a lack of consensus on the explanation provided.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the reasons for the existence of nodal surfaces. Multiple competing views are presented, with some focusing on general rules and others on more specific interpretations of electron behavior.

Contextual Notes

Some assumptions regarding the behavior of electrons and the nature of wavefunctions remain unaddressed, and the discussion reflects varying levels of understanding and confidence among participants.

Who May Find This Useful

This discussion may be of interest to students and enthusiasts of quantum mechanics, atomic theory, and those exploring the behavior of electrons in atomic structures.

why there is a nodal surface in 2s suubshell ?
 
Chemistry news on Phys.org
Why not?
 
All orbitals of hydrogen like atoms with the same main quantum number n have the same number of nodal surfaces, namely n-1.
 
No i am not asking about how many nodal surfaces are there ? but instead what is reason beside having a nodal surface
 
Energy rises the more the wavefunction wiggles. This also means more nodes

I do have a different but up to what extent its true i don't know i.e
1) as know that an atom is electrically neutral where the whole mass of nucleus is positive charge and the space around the nucleus has electrons which balance the positive charge of the nucleus so the positively charged nucleus attarcts strongly the negavetively charged electrons into the nucleus and may be the atom collapses
2)and if the electron is in continuous motion it emits energy and spiral down to nucleus
so the electron is confined to some region around nucleus so as to get attracted towards nucleus nor spiral into nucleus that is where wave function is positive and that is orbital and may in the nodal surface the electrons r not comfortable with their position so there no eletrons in nodal surface i.e wave founction -zero
I AM RIGHT?
