For 2.29 it gives orbitals and the block of the orbital

for example
4p orbital
It asks how many electrons are available at this orbital?
I got 6 electrons for 4p, but I'm not sure if I did this right can somone explain the correlation of orbitals and blocks to electron availability ?

I used the periodic table is this correct ?

Congratulations! ^_^
Saying 6 electrons in 4p is correct.

Think of it like orbital notation if you took high school chemistry but usually in the p orbitals, 6 electrons are needed to be filled to the brim with the electron because p has 3 orbital spaces in which the orbital must be filled with 2 electrons going in the opposite direction.

Or an alternative way is to use electron configuration in which we use 1s2 2p6 as a layout to figure out 4p in which all p orbitals must have 6 electrons in order to move on to another orbital level or to be completely satisfied.

I hope this helps. Please correct me if I got some parts of the concept wrong. It is a little bit hard to explain but just know electron configuration is applied to orbital notation.

In order to know how many electrons there are you would have to know the value of l, and ml.

For example in (a) it gives you 4p-orbitals. With "p" you know that l is 1 because 0,1,2,3 corresponds to s,p,d,f respectively. And ml is -1,0,1. There are three subshells because there are three ml values. And so there are two electrons per orbital so 2x3=6.
