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.
The first transition series represents the filling of the orbital?
The first transition series includes the filling of the 3d sublevel orbitals in transition metal elements from Scandium (Sc) to Zinc (Zn). These elements gradually fill the 3d orbital with electrons as they progress across the period, leading to the formation of various oxidation states and colorful compounds due to the presence of partially filled d orbitals.
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.
Maximum number of electrons in a 3d orbital is?
There can be a maximum of 10 electrons in a 3d orbital.
Why does a 4s electron have higher energy than a 3d electron in a chromium atom?
A 4s electron has higher energy than a 3d electron in a chromium atom because of the way electrons fill energy levels. In chromium, the 4s orbital is filled before the 3d orbital due to the stability gained from having a half-filled or fully-filled d orbital. This results in the 4s electron having higher energy than the 3d electron in a chromium atom.
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.
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.

Why do d orbital start to fill?
d orbitals begin to fill after the s orbitals of the same principal energy level are filled, specifically starting from the 3d orbitals after the 4s orbital. This occurs due to the energy levels of the orbitals; while the 4s orbital is filled before the 3d, the 3d orbitals have a higher energy level compared to 4s once the 3s and 3p orbitals are filled. As electrons are added to an atom, they occupy the lowest available energy orbitals first, which is why d orbitals fill after the s and p orbitals of the preceding energy level.
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.

The first transition series represents what?
The 3d orbital! ...Sexy thang...
Why does the 4s orbital fills before the 3d orbital?
the 4s orbital is lower in energy than the 3d orbitals
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 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.
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 does an element lose 4S electrons before 3D electrons?
An element loses 4s electrons before 3d electrons because the 4s orbital has a higher energy level (n value) than the 3d orbital. When an atom loses electrons to form a cation, it tends to lose the electrons from the outermost shell first, which in this case is the 4s orbital.
