what information do you get from principle quantum number |
|
Answer» It tells the main energy level occupied by the electron. moreover give information about main energy level. it is 5 marks question Principle quantum number:•Given by- Bohr•it represents the name, size and energy of the shell to which electron belongs.•indicates the distance of electron from the nucleus.•The value of n lies between 1 to ∞.i.e., n= 1,2,3,4....∞ =K,L,M,N.....•Greater the value of n greater is the distance from the nucleus. r=0.529×n²/Z A° r1<r2<r3<r4<....•Greater the value of n is greater is the energy of shell. E= -13.6×Z²/n² eV/atom E1<E2<E3<....•The angular. momentum of revolving electron is mvr=nh/2π•The number of electrons in a perticular shell is equal to 2n². |
