atomic structure 2
i saw two formulas of angular momentum of electron
1. [l(l+1)]^1/2 whrer l is azinuthal quantum number
2. nh/2pi where n is and integral multiple and also principle quantum number
whats the diff between the two

Note for OP
+solved @user1 @user2... to close the thread when your doubt is solved. Mention the users who helped you solve the doubt. This will be added to their stats.nh/2pi is for hydrogen like spe\cies, bohr model based
the one with the square root comes from quantum mech and is the actual representation
details are in atkins, i recommend that one checks that out only after doing some calculus and also complex numbers
ohhh
in some books its mentioned as [l(l+1)]^1/2 *(h/2pi) as well
whats that
yes that is the right value
bohr ka ignore
read atkins for details ;D like there is a hamiltonian operator for energy, there is another for angular momentum (capital L cap)
this is an eigen function, just like the hamiltonian operator
have done calculus but not complex
will check that out later
unlike reguilar momentum which is NOT an eigen function
eigen function - second differential gives you the same function with some constant
can you please disable this timer thingy , its irritating
like acosmx, differentiate it twice, you get k cosmx (k = -am2cosmx)
haan the timer is here to make this a discussion and not a chat like thing :Dintentional hai. khair, again - read atkins if you wanna know more (or any site that explains quantum mech properly!)
the bohr thingy se zyada accurate is this.
but for hydrogen like species i should follow nh/2pi only right
nh/2pi is solely for hydrogen and hydrogen like atoms
For Bohr
The other one is the quantum mechanical model and it's slightly more universal.
ohhk
got it
