## Quantum Numbers :

The set of quantum numbers are able to give us information about the position and energy of electrons present in an atom.

There are four quantum numbers –

• Principal quantum number represented as n
• Azimuthal quantum number represented as l
• Magnetic quantum number represented as m{eq}_{l} {/eq}
• Spin quantum number represented as m{eq}_{s} {/eq}
• The shape of a orbital is given by azimuthal quantum number.

Rules:

• n has an integer value greater than zero and gives valence shell number
• l has values from 0 to n – 1
• m{eq}_{l} {/eq} has values from –l to +l
• m{eq}_{s} {/eq} has values of -1/2 and +1/2.
• Experimental aspects associated with the two magnetic isotopes of nitrogen, 14N (natural abundance = 99.6%, spin quantum number = 1) and 15N (natural abundance = 0.4%, spin quantum number = 1/2) are discussed briefly. General relationships of molecular structure to nitrogen chemical shifts and spin-spin coupling constants involving 15N are presented. The utility of nitrogen NMR for examining molecular dynamics is described. Illustrations are provided that are chosen largely from organic and biochemistry.

## Question:

What set of quantum numbers describes the highest energy electron in the ground state of a nitrogen atom?

## FAQ

How do you find the quantum number?

Look at the Periodic Table of Elements and find the element that you want to know the quantum number for. Find the principal number, which denotes the element’s energy, by looking in which period the element is found. For example, sodium is in the third period of the table, so its principal quantum number is 3.

What are the 4 quantum numbers?

In atoms, there are a total of four quantum numbers: the principal quantum number (n), the orbital angular momentum quantum number (l), the magnetic quantum number (ml), and the electron spin quantum number (ms).

What is the spin quantum number of nitrogen?

Experimental aspects associated with the two magnetic isotopes of nitrogen, 14N (natural abundance = 99.6%, spin quantum number = 1) and 15N (natural abundance = 0.4%, spin quantum number = 1/2) are discussed briefly.

What is the quantum number for oxygen?

 Chemical properties. The oxygen atom in its quantum mechanical ground state has the electronic configuration 1s22s22p4. The ground state atom is in a 3P state, i.e., it is an electron-spin triplet (S = 1) and has orbital angular momentum quantum number L = 1.
