In any atoms, the outermost electrons are those that have the highest value of the

A

principal quantum number

B

azimuthal quantum number

C

magnetic quantum number

D

spin quantum number

Text Solution

Verified by Experts

The correct Answer is:
A
The outermost electrons have the greatest influence on the properties of elements. Adding an electron influence `d`-orbital results in less striking changes in properties than adding an electron to an outer `s-` or `p-`orbital.
