Question

which quantum number solely determines the allowed energy for H atom ? Write the expression for energy and hence explain the terms involved there in .​

Answer 1

Answer:

hope it's help you...

Explanation:

The only quantum number you need to determine the energy of an electron for H atoms is n.

In any atom or ion that has more than one electron, there is shielding (repulsion between electrons) which complicates the calculation and you need all the quantum numbers and a computer for those.
