Best Answer

The orbital will be described with a number, followed by a letter, which may have a suffix. The number is the principal energy level.

For example 2p, principal energy level 2; 5d principal energy level 5; 1s principal energy level 1.

Why does the 4S orbital begin to fill before the 3D orbital?

Electrons occupy orbitals in a definite sequence, filling orbitals with lower energies first. Generally, orbitals in a lower energy level have lower energies than those in a higher energy level. But, in the third level the energy ranges of the principal energy levels begin to overlap. As a result, the 4s sublevel is lower in energy than the 3d sublevel, so it fills first.

What is the orbit around an atom's nucleus?

We find electron orbitals around an atomic nucleus. The orbitals are actually Fermi energy levels. They are not "rigid" or "fixed" structures or specific "places" around the atom's nucleus, but are areas of probability with a constant quantum mechanical "designator" that fixes their energy level. The "sum" of the energy levels in which electrons orbit forms the orbital cloud or electron cloud around the atom.

Why does 4s orbital have low energy than 3d orbital?

that's not a proper question i guess.. it's an obvious thing that it's having less energy that's why it's lower energy level while 3d is having more energy than 4s. Don't go on the numbers 3 and 4. you might be thinkning 3 comes before 4 so 3 should be filled firstly but it's not like that......... we follow here Aufbau priniple which state that shell having less energy will be filled firstly will electron and then electrons will enter in the higher energy orbit......
