Question

write note on principal quantum number​

Answer 1

Answer:

the principal quantum no tells us about the energy of shell determines the size and energy of the orbital.there is always a positive integer value for n like n=1,2,3

• the information which are obtain from principal quantum number
• it tells us about the shell to which the electron belongs
• it specifies the size of shell that is size of orbital is directly proportional to principal quantum number
• it also tells about the maximum number of electrons that the shell can a accommodate is 2n^2
