What is the significance of principal quantum number |
|
Answer» PRINCIPAL quantum number(n) can have values 1,2,3,4 etc.It can give an IDEA about the size and energy of an orbital. It identifies the energy levels or the shell.n=1,2,3,4 etc n=1 1st energy level K shell AND SO ON The number of orbitals allowed in each shell is given by n2. All orbitals of a given value of n constitute a SINGLE shell. THUS IT DETERMINES SIZE. !!! Thank you |
