What does the principal quantum number tell and what is its range
Size and Energy
as n inc. Size and energy inc.
n=1,2,3,4,...
What is the second quntum number and what is its range
l=subshell or azimuthal quantum number
shape(and energy) of an e's orbital
l=0,1,2,3,..., n-1
l=0 s subshell, l=1 p, l=2 d, l=3 f
if the azimuthal quantum number is 0 what subshell are we in
l=0 is the s subshell
if the azimuthal quantum number is 1 what subshell are we in
l=1 is the p subshell
if the azimuthal quantum number is 2 what subshell are we in
l=2 is the d subshell
if the azimuthal quantum number is 3 what subshell are we in
l=3 is the f subshell
What is the third quantum number
the orbital quantum number
range ml= -L to L
tells us how many orbitals (places for e pairs) a subshell has
if l=0 (s subshell) ml=0 so one orbital in the s subshell
If the azimuthal quantum number is 1, what subshell are we in and how many orbitals does it have?
l=1 p subshell
ml= -L to L > -1,0,1 so three orbitals
What is the spin quantum number and what are its values
spin of electron in an orbital. Spin is either +.5 or -.5
diamagnetic
an atom that has all of its electrons spin paired. Must contain an even number of electrons
is there a magentic field in diamagnetic materials
no, all of the electrons are spin paired to the net magnetic field is 0
will a diamagnetic material be attracted or repelled by an external magnetic field
repelled-no net magnetic field. It is pretty weak though
paramagnetic
not all of an atomes e's are spin paired. They have permanent magnetic dipoles
will a paramagnetic material be attracted or repelled by an external field?
attracted
