In the case of chromium (Cr), the electron configuration of 3d54s1 is more stable than 3d44s2. A half-filled sublevel is more stable than a sublevel that is less than half full. In the case of copper (Cu), the electron configuration of 3d104s1 is more stable than 3d94s2, again because a full sublevel and a half-filled sublevel is more stable.

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.


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 is the electron configuration for copper 1s22s22p63s23p63d104s1 instead of 1s22s22p63s23p63d94s2?

The electron configuration for copper is 1s22s22p63s23p63d104s1 because copper preferentially fills its d orbital before the s orbital to achieve a more stable half-filled d shell. This configuration results in lower overall energy for the atom, making it more energetically favorable.


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.


What is the 4S orbital?

The 4s orbital is a type of atomic orbital that is part of the fourth energy level in an atom. It has a spherical shape and can hold up to 2 electrons. The 4s orbital is lower in energy than the 3d orbital in the periodic table.


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.


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


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.
