Question

which is more has the highest energy and why ?
5p 5d 5f 6s 6p​

Answer 1

Answer:

5f

Explanation:

Here the rule will be n+l

n = principal quantum number

l =. s p d f

0 1 2 3

Now 5p = 5+p

= 5+1

= 6

5d = 5+d

= 5+2

= 7

5f = 5+f

= 5+3

= 8

6s = 6+s

= 6+0

= 6

6p = 6+p

= 6+1

= 7

Here 5f is having highest value.

So, 5f is having highest energy.
