I would think the s orbital, because it is closer to the nucleus, and because the outer energy level holds more energy than the inner ones.
In molecular orbital theory, the HOMO (highest occupied molecular orbital) is the highest energy level that contains electrons, while the LUMO (lowest unoccupied molecular orbital) is the lowest energy level that does not contain electrons. The difference between the HOMO and LUMO energy levels determines the reactivity and stability of a molecule.
The lattice energy of lithium iodide is typically larger than its heat of hydration. This means that more energy is required to break the ionic bonds in the solid lattice of lithium iodide than is released when the ions are hydrated in solution.
Lithium atoms contain one unpaired electron. Two of the three total electrons in a lithium atom are paired in its lowest energy s orbital, which can contain only two.
The highest occupies energy level in aluminum is the 3rd energy level. Its electron configuration is 1s22s22p63s23p1.
3p is the highest "occupied" orbital of an "unexcited" neutral Silicon atom.
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.

Among the alkali metals, lithium has the highest ionization energy. This is because it is the smallest alkali metal, so the outermost electron is held more tightly due to increased nuclear charge and decreased atomic size.

after the s orbital of the next highest energy level
The lattice energy of lithium iodide is typically larger than its heat of hydration. This means that more energy is required to break the ionic bonds in the solid lattice of lithium iodide than is released when the ions are hydrated in solution.
based on the (n+l) value , we can calculate the energies of the orbitals in the sublevels of an orbitfor ex if we seen the energy of 2s orbital is 2 because nvalue is 2 and l value is 0
Lithium atoms contain one unpaired electron. Two of the three total electrons in a lithium atom are paired in its lowest energy s orbital, which can contain only two.
The element that has the highest second ionization energy is Li. When you remove the first electron from Li you are down to the 1s orbital. They are harder to remove because they are closest to the nucleus.
The highest occupies energy level in aluminum is the 3rd energy level. Its electron configuration is 1s22s22p63s23p1.
