What comes after 3p in the atomic orbital?
After the 3p orbital, the next atomic orbital is the 4s orbital. In the order of filling according to the Aufbau principle, the 4s orbital is filled before the 3d orbital. Following the 4s, the 3d orbitals are filled, and then the 4p orbitals come next.
Why does 4s orbital start filling while 3p orbital is empty?
The electrons fill in the lowest energy orbital that is available. Electrons in the 4s orbital have a lower energy level than electrons in the 3p orbital, so the 4s orbitals are filled with electrons first.
How many electrons can 4s orbital hold?
The 4s orbital can hold a maximum of 2 electrons.
Is that 4s or 3d orbital to which an excited electron from 3p would first go?
4s, as it is lower in energy.. s then d
Why 4S orbital is filled before 3d orbital during writing electronic configuration Explain with the help of n l rule?
4s-orbital will be filled prior to 3d-orbital.ORBITALnl(n+l)4s404+0 = 43d323+2 = 5Since 4s-orbital has least value of (n+l), therefore ,it will occupy electrons before3d-orbital.The order of increasing of energy of orbitals can be calc. from(n+l) rule or 'Bohr bury rule' According to this rule, the value of n+l is the energy of the orbital and such on orbital will be filled up first. e.g. 4s orbital having lower value of(n+l) has lower energy than 3d orbital and hence 4s orbital is filled up first. For 4s orbital, n+l=4+0=4 For 3d orbital, n+l=3+2=5,therefore 4s orbital will be filled first.
Why does the 4s orbital fills before the 3d orbital?
the 4s orbital is lower in energy than the 3d orbitals
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, as it is lower in energy.. s then d
What is the atomic orbital after 4s?
After the 4s orbital, the next orbital in order of increasing energy is the 3d orbital. The 3d orbital has a more complex shape compared to the s and p orbitals and can hold up to 10 electrons.
Why are the valence electrons of calcium in the 4s orbital not the 3d orbital?
Valence electrons occupy higher energy levels first before moving to lower energy levels, according to the aufbau principle. In calcium, the 4s orbital has lower energy than the 3d orbital, so valence electrons fill the 4s orbital first before the 3d orbital.
What is the orbital diagram for V5?
The orbital diagram for V5 consists of five electrons in the 3d orbital and no electrons in the 4s orbital.
Why do you believe that the valence electrons of calcium and potassium reside in the 4s orbital rather than in the 3d orbital?
The 4s orbital is energetically lower than the 3d orbital, so electrons preferentially occupy the 4s orbital first in atoms like calcium and potassium. Electrons fill orbitals based on their energy levels, following the Aufbau principle, which explains why the valence electrons of these elements reside in the 4s orbital.

Why is not there 3d2 instead of 4s2?
In the electron configuration of an atom, the 4s orbital is generally filled before the 3d orbital due to the lower energy level of the 4s orbital. This follows the Aufbau principle, where electrons fill orbitals in order of increasing energy. Thus, in the electron configuration of an atom, the 4s orbital is filled before the 3d orbital, leading to the configuration 4s2 instead of 3d2.
