Question

How many electrons can s,p,d,f hold?

Answer 1

`2, 6, 10, 14` respectively

Explanation:

If `ℓ` is the angular quantum number of subshell then maximum electrons it can hold is `2(2 ℓ + 1)`

`underline(bb("Sub-shell" color(white)(.....) ℓ color(white)(.....) "Maximum electrons"))`
`color(white)(.....)"s" color(white)(..............) 0 color(white)(............) 2(2(0) + 1) = 2`
`color(white)(.....)"p" color(white)(...............) 1 color(white)(............) 2(2(1) + 1) = 6`
`color(white)(.....)"d" color(white)(...............) 2 color(white)(............) 2(2(2) + 1) = 10`
`color(white)(.....)"f" color(white)(....._........) 3 color(white)(............) 2(2(3) + 1) = 14`
