FEBRO 22 23 24 25 26 27 28 Quantum Plumbercs 022-343 DAYS Quantum numbers are the Constants which are used to solve schiconolfgere wave equation. and explaines the orbital Concept of atoruke Model. ie shape, size, orcientation & spion of the electreon. The quantum numbers are helpful to identity the energy level, orchital, sabshell available to an electroon. There are 4 quantum numbers. 1. Principal Quantum Number (7) 2. Azimuthal Quantum Number() 3. Magnetic Quantum Neumben (m) 4. Spin Quantum Numbere (5) Principal Quantum numbere (n) = This quantum neembers is abko Called as Hadial quanteem numbers. This quanteers mumbere designated as 'n gives the no of energy level to which the electrons belongs. It can have positive whole number except zerco. The value of designated boy capital rumben a shell which is =1 → K-shell2 → L-sheu M-sheu 7=4 N-shell (11) The principal quanteers numbere helps to determine the nucleurage average distance of an election from the 'n also determines the energy of the & in an arbit. 21² me4z2 (iv) n=1 state have Lowest energy of con electron. This state is called ground state. 7>1 State is Called excited state. 24 SUNDAY (v) The energy difference bet 2 states. ΔΕ = Ε=2 - En=1 E (vi) With the help of on-value we can calculate the maximum no.appresent in a shell. use using 2n2 formula. 2n² e 1=K-shell → 2x12=2 2=L-shell 2x22=8 3=M-shell →2x32=12. 4-N-shell →2x4²-32 This quantum number describes the energy and position af an e in a shell. ② Azimuthal Quantum Number El) (1) Each shen Consists of a number of subshells which cerre specified by a secer numberr, specified food secondary quantem. (11) The value of 'I'depends upon the value of 'bi. for a zero. given value of in, I can have values from (11) The Ives have Values from Zesto. and is designated as subfihell, ton small lettere sipid, b... - - Subshell 1 P-lebshell 2 d subshell 3 - 6 scebshell (IN) A subshell her According to the shell no. the subshells are present. value valuecep 0,1 0,1,2 0, 1,2,3 Subshell AS 25, 2P 35 30, 30 43, 49,401,46 no. of subshen (4) We Can Calculate the no af e in a subshell with the help of formula 2(21+1) 1:0, Ssubshell has 20 p subshell has 6 -2 4-subshell hay 10 3 subshell has 14 8. Magnetic Quantrem Neembers (m) Each subshell is Composed of orcbitals designated by dibberent values cef m. The value of m' reanges from 1 to te through Zeno (0) 7 number of orchital in an subshell / shel =(22+1)
