Principle Quantum number describes?a)Size of the orbital.b)Shape of or...
Explanation:
The principle quantum number is denoted by 'n' and determines the size or energy level of an orbital. It is the most important quantum number in determining the properties of an electron in an atom.
Size of the orbital:
The principle quantum number determines the size of the orbital. The higher the value of n, the larger the size of the orbital and the farther it is from the nucleus. The size of the orbital increases as the distance from the nucleus increases.
Energy of the orbital:
The principle quantum number also determines the energy of the electron in the orbital. The higher the value of n, the higher the energy of the electron. This is because the electron is farther from the nucleus and experiences less attraction to it, making it easier to remove.
Number of orbitals:
The principle quantum number also determines the number of orbitals in a particular energy level. The number of orbitals in an energy level is equal to n^2. For example, the first energy level (n=1) has only one orbital, while the second energy level (n=2) has four orbitals.
Conclusion:
In conclusion, the principle quantum number is a fundamental property of an electron in an atom that determines the size, energy, and number of orbitals in a particular energy level. It is an essential concept in quantum mechanics and is used to explain the behavior of electrons in atoms and molecules.

The principal quantum number (n) describes the size of the orbital.
Example: Orbitals for which n = 2 are larger than those for which n = 1.
Example: Orbitals for which n = 2 are larger than those for which n = 1.
In detail Explanation: The principal quantum number is one of four quantum numbers assigned to each electron in an atom to describe that electron's state. Its values are natural numbers (from 1) making it a discrete variable. It is used to describe the size of the orbital.
