pauli exclusive principal

Pauli exclusive principal:

It state that an orbital cannot accomodate more than two electron .they should be opposite spin.

Question:
Define pauli exclusive principal on the basis of quantum number ?
ans.
Two electron in an atom cannot be completly identically i. e no two electron in an atom can have same value all the four quantum no.

from picture

for left side spin for right side spin
n=4 n=4
l=0, 1,2,3 l=0, 1,2,3
for s than for s than
l=0 l=0
m=0 m=0
s=+1/2 s=-1/2

Energy is inversely proportional to Stability. which shown in picture.

Radial probability distribution for p and d orbital, radial wave functions

Radial probability distribution for p and d orbital Radial and Angular wave function: the radial part of wave function depends upon quantum no. n and l and gives the distribution of electron w. r. t distance .it is governed mainly exponential term e^-Zr/na°(a not) here e based on natural log. Z Atomic number r distance from nucleus n principal quantum no. or radial quantum no. a° 0.529A° for hydrogen ( Bohr radii) the exact mathematical expression for radial part of wave function for 1s or 2s and 2p orbitals. n= 1 ,l=0 s orbital R(r) =2× (z/a°) ^3/2 ×(2-zr/a°) ×e^-zr/2a° n= 2 ,l=0 2s orbital R(r) = (z/a°) ^3/2 ×(2-zr/a°) ×e^-zr/2a° n= 2 ,l=1 2p orbital R(r) = 1√3×(z/2a°) ^3/2 ×(zr/a°) ×e^-zr/2a ° the radial wave function can be represented by plotting radial function R(r) apart distance(r)

Radial probability distribution curves

Radial probhjjhajajbability distribution curves: The probability of finding the electron is given by the quantity sie^2.By radial probability us probability of finding the electron within small Radial space around the nucleus. volume of spherical shell between radius r and r+dr =4πr^2 and probability of finding the electron will be 4πr^2dr sie^2. radial probability distribution curves are obtained by plotting radial probability at various distance from the nucleus . 1.Radial probability distribution curves for S orbital n=1, l= 0. distance from nucleus here A° is called angstrom. the probability of finding of electron in a shell is maximum at distance r=r° (r not) which is 0.529 A° for H atom. diagram shows that probability plot for 2s has(two region of high probability) or (two peaks) separated by node. we conclude that no. of high probability region in S orbital = n no. of node = ( n-1)

Physical significance of sie and sie^2

Physical significance of sie and sie^2 The wave function sie has no physical significance, it simply represents amplitude of wave while square of amplitude sie^2 represent intensity of electron. i. e sie ^2 gives probability of finding the electron in space .p the space is called atomic orbital A zero value of sie^2 means probability of finding the electron is zero and high value of sie^2 means greater chances of finding the electron . the value of sie^2 lies between 0&1. if sie^2 =1 100℅ sie^2=0 0℅
