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.

An electron in a 2s orbital is on average closer to the nucleus.
Electron in s-orbital is closer to nucleus than electron in p-orbital and electron in p-orbital is closer to nucleus than electron in d-orbital and so on. So,more energy is requried to remove electron from s-orbital than electron in p-orbital in spite of both having same principal quantum number. Similarly, p orbital will require more energy than d-orbital. this is called penetrating effect. it decreases in order s>p>d>f>... Note that Orbital should have same "n"
The next highest energy electron orbital after 3p is the 4s orbital, after which comes the 3d and then 4p orbitals.
after the s orbital of the next highest energy level

HOMO stands for highest occupied molecular orbital, representing the highest energy level at which an electron can be found in a molecule. LUMO stands for lowest unoccupied molecular orbital, representing the lowest energy level at which an electron can be promoted to in a molecule. These orbitals are important in understanding chemical reactivity and properties.

Orbital
The next highest energy electron orbital after 3p is the 4s orbital, after which comes the 3d and then 4p orbitals.
If the S orbital has two electrons and the P orbital has six you go on to the D orbital. Electron energy levels follow this format: 1s2 2s2 2p6 3s2 3p6 4s2 4p6 4d10 and so on
The K shell's 1s orbital is te first energy level of an electron.

3p is the highest "occupied" orbital of an "unexcited" neutral Silicon atom.
after the s orbital of the next highest energy level
valence electrons, there can be 1 to 8 of them in the outer s orbital and 3 p orbitals.
The charge of an electron is always −1.602176487(40)×10−19 Coulomb. If an electron is ejected from it's orbital the energy it absorbs is in the form of kinetic energy i.e. how fast it moves. If the electron goes back into an orbital it will only be allowed in an orbital that allows for it's energy. If an atom has an electron and that electron absorbs the energy from an incoming photon it may jump up to a higher orbital or it may be ejected. The ejected electron is the principle of the photo-electric effect.
