What is the second quantum number of the 3p1 electron in aluminum 1s22s22p63s23p1?

There are 4 quantum numbers that can be used to describe the space of highest probability an electron resides in.
First quantum number is the principal quantum number- n , states the energy level.
Second quantum number states the angular momentum quantum number - l,
states the subshell and the shape of the orbital
values of l for n energy shells are from 0 to n-1
third is magnetic quantum number - m, which tells the specific orbital.
fourth is spin quantum number - s - gives the spin of the electron in the orbital

here we are asked to find l for 3p1
n = 3
and values of l are 0,1 and 2
for p orbitals , l = 1
therefore second orbital for 3p¹ is 1.

I'm not sure what the answer choices are for you but, na+, k+,li+, nh4 + and no3 - are always spectator ions because they are always soluble.


when potassium carbonate and iron(iii) nitrate react, you get a precipitate of iron(iii) carbonate. so the k+ and the are spectator ions, and the iron and the carbonate are the ones that react together.


have a good night!
