<em>An electron has the same amount of energy in all orbitals is not true</em>
In an atom there are levels of energy in the skin and sub skin.
- This energy level is expressed in the form of electron configurations.
Writing electron configurations starts from the lowest to the highest sub-shell energy level.
So electrons that occupy the orbitals in the lowest sub-skin have the lowest energy level
- In the principle of Pauli's prohibition it was stated that there are no two electrons in one atom that can have the same four quantum numbers.
So suppose that there are two electrons occupying one orbital can have the same main quantum number (n), azimuth (l) and magnetic (m), then the last quantum number that is the quantum spin number (s) must be different.
So that the two electrons are different from just the quantum spin number, even though the other quantum numbers are the same.
So in one orbital only a maximum of 2 electrons is occupied, because if there is a third electron, this third electron will have the same quantum spin number as the previous electron
- The electron cloud is a visual representation of the location of electrons in an atom.
Orbital is the place around the nucleus where electrons may be found
Electron clouds show the state of electrons in their orbitals
So electron clouds can show the condition of all orbitals in an atom
The lowest energy level of an electron occupies a sub-skin of 1s which has only one orbital
Charging electrons in the sub skin uses the following sequence:
1s², 2s², 2p⁶, 3s², 3p⁶, 4s², 3d¹⁰, 4p⁶, 5s², 4d¹⁰, 5p⁶, 6s², etc.

Electric charge on the plastic cube:
Explanation:
The electric potential around a charged sphere (such as the Van der Graaf) generator is given by
where
k is the Coulomb's constant
Q is the charge on the sphere
r is the distance from the centre of the sphere
Here we have:
V = 200,000 V on the surface of the sphere, so at r = 12.0 cm
We need to find the voltage V' at 2.0 cm from the edge of the sphere, so at
r' = 12.0 + 2.0 = 14.0 cm
Since the voltage is inversely proportional to r, we can use:
This is the potential at the location of the plastic cube.
Now we can use the law of conservation of energy, which states that the initial electric potential energy of the cube is totally converted into kinetic energy when the plastic cube is at infinite distance from the generator. So we can write:
where:
q is the charge on the plastic cube
V' is the potential at the location of the cube
m = 5.0 g = 0.005 kg is the mass of the cube
v = 3.0 m/s is the final speed of the cube
Solving for q, we find the charge on the cube:
