The 3d electrons are in "3" based on their quantized energy. The 4s electrons are of higher quantized energy, thus they are in level 4. However, when lots of electrons are present, the negative-negative repelling forces the electrons in 3d are ecountering pushes them into a more energized state above 4s. It becomes even more confusing when you consider larger elements with 'f' orbitals. Also remember, this model is based on a hydrogen atom. Each atom is its own little complex arrangement of electrons that follow a general rule, not a law.

How would the 4d orbitals differ from the 3d orbitals?
The 4d orbital would be the same shape as the 3d orbital, but just a larger size. Also it would have more nodes than he 3d orbital.
In the elements in the middle section of the periodic table which orbital are the electrons being added?
the outer shell electrons of the transition elements (middle section) go into the 'd' orbital e.g. Cobalt (Co) 1s2 2s2 2p6 3s2 3p6 4s2 3d7 The 4s orbitals get filled up before the 3d orbitals because it takes less energy to fill the 4s orbital
Which orbital should fill first 4s or 3d orbital?
4s will fill first because it is at a lower energy level than the 3d level.
4s orbital is filled before 3d orbital?
The 4s orbital falls in a slightly lower energy level than the 3d orbital when it is empty so it will fill with electrons first, but when it is full of electrons it rises to be above the 3d one so that it will lose electrons first as well.
What atom is represented in the following orbital diagram 1s2s2p?
The next highest energy electron orbital after 3p is the 4s orbital, after which comes the 3d and then 4p orbitals.
Why does the 4s orbital fills before the 3d orbital?
the 4s orbital is lower in energy than the 3d orbitals
How would the 4d orbitals differ from the 3d orbitals?
The 4d orbital would be the same shape as the 3d orbital, but just a larger size. Also it would have more nodes than he 3d orbital.
In the elements in the middle section of the periodic table which orbital are the electrons being added?
the outer shell electrons of the transition elements (middle section) go into the 'd' orbital e.g. Cobalt (Co) 1s2 2s2 2p6 3s2 3p6 4s2 3d7 The 4s orbitals get filled up before the 3d orbitals because it takes less energy to fill the 4s orbital
Which orbital should fill first 4s or 3d orbital?
4s will fill first because it is at a lower energy level than the 3d level.
4s orbital is filled before 3d orbital?
The 4s orbital falls in a slightly lower energy level than the 3d orbital when it is empty so it will fill with electrons first, but when it is full of electrons it rises to be above the 3d one so that it will lose electrons first as well.
How many orbitals are within 3s 3p and 3d sub levels of the third energy levels?
There are one 3s orbital, three 3p orbitals, and five 3d sublevels.
