They are the designation for the orbitals present.
s and p orbitals in the 2nd energy level.
In a lithium atom, the energy of the 2s subshell is lower than the energy of the 2p subshell.
The valence electrons in an atom of nitrogen (N) are found in the 2s and 2p sublevels. There are a total of 5 valence electrons in nitrogen, with 2 in the 2s sublevel and 3 in the 2p sublevel.
The electron configuration of boron nitride (BN) is 1s^2 2s^2 2p^1 for the boron atom and 1s^2 2s^2 2p^3 for the nitrogen atom.
The electron configuration for an oxygen atom is 1s^2 2s^2 2p^4. This means there are 8 electrons in total, with 2 electrons in the 1s orbital, 2 in the 2s orbital, and 4 in the 2p orbital.
Fluorine has 9 electrons, which occupy 2s and 2p orbitals. Therefore, there are a total of three orbitals in fluorine (one 2s orbital and two 2p orbitals).
In a lithium atom, the energy of the 2s subshell is lower than the energy of the 2p subshell.

Levels 2p and 2s.
The electron configuration of boron nitride (BN) is 1s^2 2s^2 2p^1 for the boron atom and 1s^2 2s^2 2p^3 for the nitrogen atom.
The electron configuration for an oxygen atom is 1s^2 2s^2 2p^4. This means there are 8 electrons in total, with 2 electrons in the 1s orbital, 2 in the 2s orbital, and 4 in the 2p orbital.
The noble gas abbreviation for carbon is [He] 2s^2 2p^2, which represents the electron configuration for a carbon atom. This notation indicates that carbon has two electrons in its 2s orbital and two electrons in its 2p orbital.
In a silicon atom, there are four filled orbitals. Specifically, there are two filled in the 1s orbital and two filled in the 2s orbital.
In the ground state, a sodium atom in the second principal energy level has two sublevels completely occupied: the 2s and the 2p sublevels. The 2s sublevel can hold a maximum of 2 electrons, and the 2p sublevel can hold a maximum of 6 electrons.
The electron configuration of CCl4 is 1s^2 2s^2 2p^6 3s^2 3p^2. This means that the carbon atom has 2 electrons in the 1s orbital, 2 electrons in the 2s orbital, 6 electrons in the 2p orbital, 2 electrons in the 3s orbital, and 2 electrons in the 3p orbital.
Fluorine has 9 electrons, which occupy 2s and 2p orbitals. Therefore, there are a total of three orbitals in fluorine (one 2s orbital and two 2p orbitals).
An atom of sulfur has 16 electrons. Since the electron configuration of sulfur is 2-8-6, there are two filled energy levels (1s and 2s/2p) with a total of 10 filled orbitals (2 in 1s, 8 in 2s/2p).
The electron configuration for a nitrogen anion with a charge of -2 (N²⁻) involves adding two additional electrons to the neutral nitrogen atom. The neutral nitrogen atom has an electron configuration of 1s² 2s² 2p³. Therefore, the electron configuration for the N²⁻ ion is 1s² 2s² 2p⁵.
