Why does an electron occupy the 4s orbitals before the 3rd orbital?
Because the 4d electrons experience a lower effective charge from the nucleus at this point than the 5s electrons. Long story is that it has to do with the energy lost from spin-pairing. That means that it takes more energy to spin-pair the 5s electron than the energy difference between the 4d and 5s orbitals, so it will push the electron up to the 4d orbital since it requires slightly less energy. At the periods containing cromium and copper, this is where that effect takes place. You can demonstrate this to yourself by calculating the Z(eff) for the electrons using Slater's Rule, and you will see the change in Z(eff) for yourself.
Which of the subshells in the electron configuration of Hf behave as core orbitals?
The subshells of 1s 2s 2p 3s 3p 4s 3d 4p 5s 4d 5p 4f act like core orbitals. This understanding of the configuration of the atom helps us to understand why electrons and atoms behave the way they do.
What is the order of electron orbitals?
The order for filling in the sublevels becomes; 1s, 2s, 2p, 3s, 3p, 4s, 3d, 4p, 5s, 4d, 5p, 6s, 4f, 5d, 6p, 7s, 5f, 6d,7p.
Which elements are exception to aufbau principle other than chromium and copper?
The elements that are exceptions to the aufbau principle other than chromium and copper include molybdenum (Mo) and tungsten (W), which have a 4s orbital that is higher in energy than the 3d orbital, and silver (Ag) and gold (Au), which have a 5s orbital that is higher in energy than the 4d orbital. These exceptions are due to the electron-electron repulsion between electrons occupying the 4s and 3d orbitals, and the 5s and 4d orbitals, respectively.
Why does one electron in a rubidium atom occupy a 5s orbital rather than a 4d or 4f orbital?
in 5s it is filled but in 4d or 4s its half
How many orbitals are in 4d sublevel?
7 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.
Which of the subshells in the electron configuration of Hf behave as core orbitals?
The subshells of 1s 2s 2p 3s 3p 4s 3d 4p 5s 4d 5p 4f act like core orbitals. This understanding of the configuration of the atom helps us to understand why electrons and atoms behave the way they do.
Which is having the greater shielding effect 4s 4p 4d and 4f?
the correct order is-4s>4p>4d>4f this is because of the shape of the orbitals
How many orbitals can there be in an f sublevel?
The maximum number of f orbitals in any single energy level in an atom is 7.
How many electrons are in the 4d orbitals of Tc?
zero - after the 4s orbitals are filled at Calcium, the 3d orbitals start to fill - not until Gallium do the 4p orbitals start to fill.
How many types of orbitals are in the sixth shell?
There are 36 types of orbitals in the sixth shell.
What is the order of electron orbitals?
The order for filling in the sublevels becomes; 1s, 2s, 2p, 3s, 3p, 4s, 3d, 4p, 5s, 4d, 5p, 6s, 4f, 5d, 6p, 7s, 5f, 6d,7p.
Which elements are exception to aufbau principle other than chromium and copper?
The elements that are exceptions to the aufbau principle other than chromium and copper include molybdenum (Mo) and tungsten (W), which have a 4s orbital that is higher in energy than the 3d orbital, and silver (Ag) and gold (Au), which have a 5s orbital that is higher in energy than the 4d orbital. These exceptions are due to the electron-electron repulsion between electrons occupying the 4s and 3d orbitals, and the 5s and 4d orbitals, respectively.
Do higher energy levels have higher orbitals than lower energy levels?
Energy levels are formed into sublevels which contain specific numbers of orbitals, each of which can contain two electrons with opposite spins. The s sublevel has 1 orbital, the p sublevel has 3 orbitals, the d sublevel has 5 orbitals, and the f sublevel has 7 orbitals.
What electron could have quantum numbers n 4 l 2 ml -2 ms?
A 4d electron; that is for apex :)
