hello all =]
just been two days i started chem A level (both AS & A2) and any doubts i find ill be postin here...


so my first doubt,
can someone please clearly explain me what orbitals are ???
accordin to the definition, it says tht they are space around the nucleus where there is max. probablity of findin the electron within its orbit.
for example when n=3; l=0,1,2
so by 0,1,2 does it mean 0 from the nucleus (like coverin all the orbits in between as well> n=1 and n=2) ???

I too have just started my AS Levels.

I wish Nid was here to explain this stuff. She's the Chem Masta.  :(

ORbital:- u cn just make it clear that by understanding that they r the sub-shell of energy level.

for eg.

shell one contains oribtal - 1s(2e-) (grand Total 2e-)
shell two contains orbital - 2s (2e-), 2p(2*3 e-(px,py,pz) (grand total 8e=(2e-+6e-)
shell three contains ornital - 3s(2e-), 3p(2*3e-), 4s(2e-), 3d(2*5e-) (element in which electrons are filled in 3d would be transition metal) [grand total 20e-)

soory!
my explain skill is very poor

If you still don't understand(rare case) then I shall do my bit  :)
