Atomic Structure Flashcards
Radiation types ranges and uses
mass of electron?
9.1 x 10^-31 kg
the order of wavelnetgh of the different of EM waves
increasing order of wavelentgh
C G X U V I M R
Max KE formula for photoelectric effect
Max KE = work function - incident light energy
stopping potential formula
V(stopping) = max KE/e(charge of electron)
angular momentum relation with orbitan number
mvr = nh/2pi
radius of nth orbit formula
(n^2)/Z x 0.529 x 10^-10 m
velocity of electron in nth orbit
z/n x 2.18 x 10^6 m/s
Time period of revolution formula
T = 2πr/v
TE,KE,PE relation
TE = 1/2 PE = -KE
TE formula
- Z^2/n^2 x 13.6 eV
wavelentgh of electron transition formula(with rydbergs constant)

Rydbergs constant value
and 1/R value
109678 cm^-1
912 Angstrom
de broglie’s wavelentgh for electron shortcut
no. of orbitals in nth shell:-
max no. of electron in a shell:-
no of electron in a shell:-
no of electron in a subshell:-
no. of orbitals in nth shell:- n^2
max no. of electron in a shell:- 2n^2
no of electron in a shell:-n
no of electron in a subshell:- 2(2l+1)
orbital angular momentum with ‘l’
value of l for s,p,d,f shells
for s= 0
for p= -1,0,1
for d= -2,-1,0,1,2
for f= -3,-2,-1,0,1,23
whats pauli’s exclusion principle
no two electron can have the same set of all the four quantum number
Whats Aufbau rule
The electron are filled are filled up in various subshell in order of their increasing energies
whats hund’s rule
no electron pairing takes place in orbitals of a subshell until each orbital is occupied by one electron is parallel spin
number of radial nodes=
number of angular/nodal planes=
total number of nodes=
number of radial nodes= n-l-1
number of angular/nodal planes= l
total number of nodes= n-1
number of spectral lines
