The 3d sublevel is not filled until after the 4s sublevel, because the 3d sublevel has more energy than the 4s sublevel, and less energy than the 4p sublevel.

What is another name for the electron shell?
Orbital x ray
Difference between orbit and orbital?
axmed shOrbit is a concept from celestial mechanics and astronomy.Orbital is a concept from quantum mechanics, spectrometry, and chemistry.the circular path of rotation of electron around the nucleus is called an orbit . Whereas the region around the nucleus of an atom where probability of finding the electron is maximum is called orbital
According to Hunds' rule when electrons occupy orbitals of equal energy one electron enters each orbit until?
All the orbitals contain one electron, with the same spins.
What is the maximum number of electrons that can occupy one orbit?
2 electrons is the maximum number for an single orbital.
What is the difference between an electron shell orbital or cloud?
The shell is the principle energy level, and is defined as 1, 2, 3, etc. (or K, L, M, etc). An orbital is the spacial orientation of the orbit, such as px, py, pz, where the orbit is a p orbit, and the orbital is the x, y, or z orientation of that orbit. This is a mathematical expression of where the electron is most likely to be found. The electron cloud is more of a visual representation of the electrons surrounding the nucleus, and is based on the electron orbitals.
What is the location of electrons?
Around the atomic nucleus, on electron shells.
In what way does an orbit differ from an orbital?
An orbit is the path an object takes around another object, like a planet around a star. An orbital is the specific region around an atom where an electron is likely to be found.
What is the number of electron that can be held in the first orbit?
If you mean 'orbital' then 2. Every orbital holds 2. If you mean energy level one, then it also happens to be 2.
What is the electrons location?
Electrons orbit the nucleus of an atom. The exact location of a specific electron, however, can not be known for certain. The general area where the electron might be found is in its orbital.
What is meant by orbital?
An orbital is the orbit (energy level) in which the electron spins around an atom. The arrangement of electrons in the outer orbitals determines the physical and chemical characteristics of an element.
Light is emitted as an electron transitions from a higher energy orbital to a lower energy orbital How long does it take for the actual transition to take place?
The actual transition of the electron from a higher energy orbital to a lower energy orbital happens almost instantaneously, typically on the order of femtoseconds (10^-15 seconds). This rapid transition results in the emission of light as photons are released.
Why is there an unfilled orbit?
In any electon shell, each orbital must have one electron already present before any more can be added to any particular energy level. This is known as Hunn's Rule.
