    Nodal Surface
AI Thread Summary
The discussion centers on the presence of nodal surfaces in the 2s subshell of hydrogen-like atoms, emphasizing that all orbitals with the same principal quantum number n have n-1 nodal surfaces. The reason for having nodal surfaces is linked to the energy of the wavefunction; as the wavefunction increases in complexity (or "wiggles"), the energy also rises, resulting in more nodes. The conversation also touches on the nature of atomic structure, noting that atoms are electrically neutral with a positively charged nucleus attracting negatively charged electrons. This attraction prevents electrons from spiraling into the nucleus, leading to a confinement in specific regions around the nucleus, where the wavefunction is positive, defining the orbital. In nodal surfaces, the wavefunction is zero, indicating that electrons are not found in these regions. The explanation aligns with quantum mechanics principles, confirming that the absence of electrons at nodal surfaces is due to the nature of wavefunctions and energy considerations.

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?
 

Thread 'Humidity of a saturated NaCl solution with anticaking additive'

I want to test a humidity sensor with one or more saturated salt solutions. The table salt that I have on hand contains one of two anticaking agents, calcium silicate or sodium aluminosilicate. Will the presence of either of these additives (or iodine for that matter) significantly affect the equilibrium humidity? I searched and all the how-to-do-it guides did not address this question. One research paper I found reported that at 1.5% w/w calcium silicate increased the deliquescent point by...
