Question

9. What is nl * method? How it is useful? ​

Answer 1

Explanation:

nlx method is notation of electronic configuration. It determines principal quantum number (n), sublevel (l) and no. of electrons (x) in sublevel. It helps to predict the values of all the four quantum numbers of any electron.

Answer 2

Answer:

$nl^{x}$  the method is a technique used to write an atom's electronic configuration. where 'n' is defined as the letter s, p, d, f, etc. (i.e., primary quantum number) and 'l' is defined as the letter s, p, d, f, etc. (i.e., azimuthal quantum number), and 'x' is the number of electrons present in orbitals as defined by 'n' and 'l' values.

Illustration: As  the number of electrons in a Nitrogen atom is seven, the electrical configuration of the Nitrogen atom is as follows: $1s^{2} 2s^{2} 2p^{3}$
