nlx is a notation for the electronic configuration.
It is used to determine all the quantum values for a particular electron. ‘n’ is used to determine the principal quantum number, ‘l’ for the sublevel and ‘x’ for the number of electrons in the sublevel.
Example: Oxygen has atomic number 8,
The nlx representation would be
Final Answer:
nlx is a notation for electronic configuration and use to determine the quantum values for a electron.
