Define atomic orbital names based on atomic numbers

OpenStudy (aaronq):

atomic orbitals can be written in terms of quantum numbers, is that what your referring to?

OpenStudy (anonymous):

@aaronq im referring to the terms of quatum numbers but i just dont understand any of it

OpenStudy (aaronq):

get a periodic table out |dw:1349836168234:dw|

OpenStudy (aaronq):

the periodic table is nicely set up in blocks of orbitals

OpenStudy (anonymous):

go on

OpenStudy (aaronq):

except helium which is 1s^2

OpenStudy (aaronq):

so lets say you have Mg

OpenStudy (aaronq):

you start off from the top and make your way left to right counting every electron (b/c quantum numbers are basically electron configurations)

OpenStudy (aaronq):

Mg in it's neutral state: has 12 electrons.. so 1s^2 2s^2 2p^6 3s^2

OpenStudy (aaronq):

try one, try Phosphorous

OpenStudy (anonymous):

ok gimme a second

OpenStudy (anonymous):

1s^2 2s^2 2p^6 3s^2 3p^3 ? So it's electron configuration?

OpenStudy (aaronq):

yup thats correct. it's a little more difficult when you enter the d block because you start at 3d

OpenStudy (anonymous):

ok thanks your awesome!!!!

OpenStudy (aaronq):

haha no prob dude !
