SUMMARY

The number of nodal surfaces in an atomic orbital is determined by the principal quantum number (n). Specifically, the correct formula is n-1, meaning that for any given orbital, the number of nodal surfaces is one less than the principal quantum number. This clarification resolves the conflicting arguments presented in the discussion, affirming that the nodal surfaces are not equal to n but rather n-1.

PREREQUISITES
  • Understanding of quantum mechanics principles
  • Familiarity with atomic orbitals and quantum numbers
  • Knowledge of the principal quantum number (n)
  • Basic grasp of wave functions and nodal surfaces
NEXT STEPS
  • Study the relationship between quantum numbers and atomic orbitals
  • Explore the mathematical derivation of nodal surfaces in wave functions
  • Learn about the significance of nodal surfaces in chemical bonding
  • Investigate the implications of nodal surfaces on electron distribution in atoms
USEFUL FOR

Students of chemistry, physicists, and educators seeking to deepen their understanding of atomic structure and quantum mechanics.

Hey just need a quick clarification here.

I am reading conflicting arguments. One argument states that to find the nodal surfaces of an orbital you take the result of n-1 the other argument states that the number of nodal surfaces of an orbital is equal to n.

Can someone please clear this up for me? Thanks.

It's n-1, I don't know where they're getting just n.
 

Thread 'Gold hydride - what is the significance?'

I came.across a headline and read some of the article, so I was curious. Scientists discover that gold is a 'reactive metal' by accidentally creating a new material in the lab https://www.earth.com/news/discovery-that-gold-is-reactive-metal-by-creating-gold-hydride-in-lab-experiment/ From SLAC - A SLAC team unexpectedly formed gold hydride in an experiment that could pave the way for studying materials under extreme conditions like those found inside certain planets and stars undergoing...
