vand Magnetic quamnlum numbers ?(I need this for 7 marks please give detailly )​

Answer 1

Hello ❤

• Principal Quantum Number :-
• denoted by n.
• n = 1,2,3----infinity but n is not equal to zero or fractional number.
• Gives information about number of orbits or shells.
• Maximum number of electrons in an orbit = 2n^2.
• n=1, max e-= 2
• n=2, max e = 8 and so on.

• Magnetic Quantum Number :-
• How many orientations a sub shell has is known by orientation quantum number or magnetic quantum number.
• m = 2L + 1
• Value of m ranges from -L to +L for a subshell.
