They are the designation for the orbitals present.
s and p orbitals in the 2nd energy level.
Levels 2p and 2s.
The second shell is 2S, 2P which can hold 8 total (2+6).
a. [He]2s(squared) 2p(cubed)1s^2 2s^2 2p^3
5. Nitrogen has 7 electrons total, 1s has 2, 2s has 2 and 2p has 3. The highest engergy leve is 2, containing both 2s and 2p, so 2+3=5
1s^2 2s^2 2p^6 3s^1
The 1s, 2s, 2p and 3s

An atom with six protons would be a carbon atom. It would have six electrons, two in the first shell, the 1s orbital, and four in the second shell, two 2s electrons and two 2p electrons. The 2p orbital is further out than the 2s, so depending how detailed you want to be there are either four in the second shell, or two in the 2p orbital.
two 2s electrons (2s2 ) and 2p electrons 2p2 so 4 all together
1s^2 2s^2 2p^6 3s^1
You can tell the difference between 2s sub-shell and 2p sub-shell by checking their energy levels whereby a 2p orbital has a higher energy level compared to a 2s orbital.
You can tell the difference between a 2s sub-shell and 2p sub-shell from their energy levels, because a 2p sub-shell is a higher energy level than a 2s sub-shell.
Nitrogen has 5 valence electrons. Valence electrons are the electrons that are found in the outer most shell of an atom, and are consequently the electrons that move from atom to atom in the formation of compounds. The reason for this is a result of the electron configuration. A nitrogen atom has 3 orbitals; the 1s orbital, the 2s orbital, and the 2p orbital. In this case, the 2s and 2p orbitals are the valence orbitals, as they have the electrons with the most energy. With 7 protons, a neutral nitrogen atom has 7 electrons. The s orbitals can only hold 2 electrons, and the p orbitals can hold up to 6 electrons. The 1s orbital is filled first, leaving five electrons, then the 2s orbital is filled, leaving 3 electrons, and then these remaining electrons fill the 2p orbital halfway. There are a total of 5 electrons in the 2s and 2p orbitals, and since these orbitals have the most energy, there are 5 valence electrons.
