The maximum number of electrons in any s sublevel is 2, irrespective of what the principal quantum number, i.e., the number before the s in an electron configuration, may be.
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.
In the ground state of a chlorine atom, there are 3 occupied sublevels: 1s, 2s, and 2p. Each sublevel can hold a maximum of 2 electrons, giving a total of 2 + 2 + 6 = 10 electrons.
There are two sublevels in the second principle energy level. The s sublevel has one orbital and the p sublevel has 3, for a total of 4 orbitals.
Two. The ground state configuration of Sulfur is [Ne] 3s23p4. According to Hund's rule, the p orbitals must fill up separately first. This results in the first 3 electrons going into separate orbitals, and the fourth then doubles up with the first, leaving the other two p orbitals with unpaired electrons.
The highest occupied energy level in Beryllium is the 2s orbital. Beryllium has 4 electrons, with 2 electrons in the 1s orbital and 2 electrons in the 2s orbital.
The 2s sublevel can hold a maximum of 2 electrons.
The 2s sublevel can hold a maximum of 2 electrons.
In an atom of magnesium, the valence electrons are found in the 3s sublevel. Magnesium has an atomic number of 12, which means it has two electrons in the 1s sublevel, two in the 2s, and eight in the 2p, leaving two electrons in the 3s sublevel as its valence electrons.
The sublevel of aluminum (Al), which has an atomic number of 13, is 3p. In its electron configuration, aluminum has the arrangement of electrons as 1s² 2s² 2p⁶ 3s² 3p¹, indicating that the outermost electrons are located in the 3p sublevel.
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.
There are two energy sublevels in the second energy level - the s sublevel and the p sublevel. The s sublevel can hold a maximum of 2 electrons, while the p sublevel can hold a maximum of 6 electrons.
In an atom of magnesium (Mg), the valence electrons are found in the 3s sublevel. Magnesium has an atomic number of 12, and its electron configuration is 1s² 2s² 2p⁶ 3s². The two electrons in the 3s sublevel are the valence electrons that participate in chemical bonding.
Levels 2p and 2s.
Iron (Fe) has an atomic number of 26. In terms of electron configuration, its sublevel notation is 1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d⁶. This indicates that iron has two electrons in the 4s sublevel and six electrons in the 3d sublevel, with the 3d sublevel being the highest energy level that is partially filled.
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.
2s: 2 electrons 5p: 6 4f: 14 3d: 10 4d: 10
The 2s orbital can hold a maximum of 2 electrons.
