what is n in chemistry
- In lanthanides and actinides, how are the f orbitals filled relative to s and d orbitals with different n values?
- How do the energy levels of multi-electron atoms differ from those of hydrogen due to electron-electron interactions (shielding and penetration), even for orbitals with the same n?
- How do metal ions play crucial roles in many biological processes by coordinating with biomolecules, and how do their electronic configurations (determined by n) influence their reactivity and interactions?
- How does the concept of n help explain the shapes of molecules based on VSEPR theory?
- How does the intensity of spectral lines relate to the population of different energy levels (determined by n) in stars?
- Does n directly determine the shape, or does it influence the distribution of electron density which then determines shape?
- How do these periodic trends reflect the changes in effective nuclear charge and the distance of valence electrons from the nucleus as n increases down a group and the number of protons increases across a period?
- How does n relate to the spin quantum number (ms)?
- How does electronegativity generally vary across a period and down a group, and how is this related to n?
- How does the energy difference between two levels with different n values relate to the frequency or wavelength of emitted or absorbed light?
