In every atom there are principle energy levels, sub-levels and atomic orbitals. The principle energy levels are often those first taught when studying chemistry. They correspond to how close the electrons are to the nucleus. The first principle energy level is closest to the nucleus and can hold a mxaimum of two electrons. The second principle energy level is slightly further away from the nucleus and can hold a maximum of eight electrons. The third energy level is even further away and can hold a maximum of ten electrons.
Each principle energy level is comprised of different sub-levels: s, p, d and f. The s sub-level can hold a maximum of two electrons; , p a maximum of 6; d, a maximum of 10 and f, a maximum of 14 (although the f sub-level is only present in the lanthanide and actanide series). Sub-levels all have different energies and electrons fill sub-levels in order of lowest energy to highest. The first principle energy level has one sub-level, the 1s sub-level. The second principle energy level has two sub-levels, 2s and 2p. The third principle energy level has three sub-levels, 3s 3p and 3d. (However, the 4s sub-level is filled before the 3d sub-level, which is a different matter which cannot be explained quite so simply.)
Now, each sub-level is comprised of atomic orbitals which define the approximate boundaries of the electron orbit. Each orbital can hold up to two electrons, so a s sub-level has one orbital; a p sub-level has three orbitals; a d sub-level has five orbitals and a f sub-level has seven. This explanation is really quite brief as there is so much more information concerned with principle energy levels, sub-levels and atomic orbitals, which I suggest you look up elsewhere. =)

What is the difference between the homo and lumo energy levels in molecular orbital theory?
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 major difference between a 1s orbital and a 2s orbital is that?
the 1s orbital is closer to the nucleus and has a lower energy level compared to the 2s orbital. Additionally, the 2s orbital has a slightly higher energy, larger size, and can hold more electrons than the 1s orbital.
What is the difference between an orbital and a shell in an atom?
In an atom, an orbital is a region where electrons are likely to be found, while a shell is a group of orbitals with similar energy levels. Orbitals are specific locations within a shell where electrons can exist.
Why electrons are removed first from 5d than 4f orbital in lanthanides?
Electrons are removed first from the 5d orbital than the 4f orbital in lanthanides because the 5d orbital has higher energy than the 4f orbital. In lanthanides, the energy difference between the 4f and 5d orbitals is small, making it more energetically favorable to remove electrons from the 5d orbital first before the 4f orbital.
What types of atomic orbitals are in the second principal energy level?
An s orbital
What is the difference between orbital and suborbital space flights?
An Orbital space flight simply means that you have accelerated a space craft fast enough so it stays in orbit (cicular path) around the Earth. A suborbital flight means you have reached the limit of space (anything over 100 km high) but not enough speed to completely circle the Earth.
What is the difference between an orbital motor and a conventional motor?
Both
What is the main difference between a belt sander and an orbital sander?
The main difference between a belt sander and an orbital sander is the sanding motion they use. A belt sander moves in a continuous loop, while an orbital sander moves in a circular motion.
What does the P stand for?
I'm fairly certain you are referring to the P suborbital. This is a suborbital within an electron orbital level, and contains 6 electrons, 3 pairs. I believe its a bar bell shaped orbital, but I could be wrong. You also might be referring to the group of elements on the Periodic Table in families III-VIII. They are there because they all have empty P level suborbitals.
What is the difference between a 2s orbital and a 3s orbital?
The main difference between a 2s orbital and a 3s orbital is their energy levels. A 3s orbital is at a higher energy level than a 2s orbital. Additionally, the 3s orbital has a larger size and higher probability of finding an electron farther from the nucleus compared to a 2s orbital.
What is the difference distance wise between low orbital spaceflight and sub orbital spaceflight?
Sub-orbital space flight reaches space while low orbital spaceflight attain sufficient velocity to go to space.
How many p electrons are possible in any orbital?
6 electrons can ocupy the 2p, 3p, 4p, and so on. each p subshell has 3 orbitals, and each orbital can hold up to 2 electrons, so each p subshell can hold up to 6 electrons total.
What is the difference between the homo and lumo energy levels in molecular orbital theory?
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.
what is the meaning of p orbital?
It is an orbital shape for electrons. It is further split into Px, Py and Pz. Each suborbital can hold 2 electrons, so P can hold 6 total. The shape of each is a dinbell or an infinity/8 sign, on the axis in question
The major difference between a 1s orbital and a 2s orbital is that?
the 1s orbital is closer to the nucleus and has a lower energy level compared to the 2s orbital. Additionally, the 2s orbital has a slightly higher energy, larger size, and can hold more electrons than the 1s orbital.
What is the difference between the 2px orbital and the 2py orbital?
The px orbital has a magnetic quantum number value of -1, and the py orbital has a magnetic quantum number value of 0.
What is the difference between a random orbital sander and an orbital sander?
A random orbital sander moves in a circular and random pattern, reducing the risk of swirl marks on the surface being sanded. An orbital sander moves in a circular pattern, which can sometimes leave swirl marks on the surface.
