 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
