The principle that summarises that no two electrons having the same space can have same quantum numbers.
Answer to Problem 1CQ
The Pauli Exclusion Principle states that no two electrons occupy the same space can have the same quantum numbers.
Explanation of Solution
The set of values which describes the electron state including the orientation of an electron, its distance from the nucleus and type of orbital, where the electron is found and its spin is known as quantum number.
There are four types of quantum number:
- Principal Quantum number
- Azimuthal Quantum number
- Magnetic Quantum number
- Spin Quantum number
The quantum number that is assigned to all electrons in an atom for the description of state of those electrons is known as Principal quantum number.
The quantum number which describes the shape of the orbital in which electron is present is known as Azimuthal quantum number.
The quantum number which describes the levels of energy in a subshell is known as Magnetic quantum number.
The quantum number which describes spin of electrons (up or down) is known as Spin quantum number.
Bonding energy depends upon the quantum
Pauli Exclusion Principle: Two electron of same atom cannot have same quantum numbers.
Let us take the example of
Conclusion:
The Pauli Exclusion Principle summarises that two electrons occupying the same space cannot possibly have the same quantum number as a whole.
