Any orbital can hold a maximum of 2 electrons
An s orbital can have a maximum of two electrons.
2 electrons is the maximum number for an single orbital.
The max. number of electrons that can fill the 3s orbital is 2.
The 2p sub-level can hold a maximum of 6 electrons. The 2p sub-level is divided into 2px, 2py and 2pz. Each of those orbitals can hold a maximum of 2 electrons. There are 3 of them and thus 6 total for the 2p sub-level.

An orbital can only occupy maximum of 2 electrons. As p orbital consist of 3 orbitals. And has 3 orientations. Px, Py, Pz. So as there are 3 orbitals so p orbital can occupy at the maximum 6 electrons regardless of principle quantum no.. In 4p 4 is principle quantum no. So it represent 4p represent the p orbital of 4th shell. So it also occupy at the maximum of 6 electrons.
Since they are p orbitals, 6 electrons are occupied in the 3p orbital. there are 3 types of p orbital, px, py and pz
Yes it does. Helium has 2 electrons in the s orbital. A s orbital can hold a maximum of two electrons.
The number of electrons usually does not equal the number of protons. Valence means outermost. In an electrically neutral atom (which in Gen Chem is the only atoms you will be dealing with) the number of outermost electrons usually does not equal the number of protons. Chlorine has 7 valence electrons but it has 17 protons and if it is electrically neutral (which in gen chem it almost always is) it has 17 electrons. Gen Chem 1: it has 2 electrons in the first shell then it has 8 electrons in the second shell then it has 7 electrons in the outermost shell Gen Chem 2: it has 2 electrons in the 1s orbital then it has 2 electrons in the 2s orbital then it has 6 electrons in the 2p orbital then it has 2 electrons in the 3s orbital then it has 5 electrons in the 3p orbital
