What feature of an orbital is related to each of the following?<br> (a) Principal quantum number (n)
raketka [301]

Principle  quantum number describes the energy of an electron and most probable distance of the electron from the nucleus.

<h3>What is the significance of principle quantum numbers and azimuthal quantum numbers?</h3>

A principal quantum number  signifies size and energy of the orbital.Azimuthal quantum number signifies three dimensional shape of the orbital.

Magnetic quantum numbers signifies spatial orientation of the orbital.

Principal quantum numbers is the quantum numbers denoted by n which indirectly describes the size of the electron orbitals. It is always assigned an integer value but its value never be 0.  The feature of a principal quantum numbers  is the energy of  an electron and  most probable distance of the electron from the nucles.
