Question

which of the orbital out of 5P, 5d,5f 6s 6p hasthe highest energy

Answer 1

highest energy in orbital is 5f

which is proved by aufbau principle..

this is your correct answer..

hope it helps...

Answer 2

Answer : The orbital that has the highest energy is, 5f

Explanation :

According to the Aufbau principle, the atom or ion that present in the ground state, the lowest energy level will be filled first before occupying the higher levels.

For example : The 1s shell will be filled first before 2s subshell.

According to this principle, the highest energy orbital will have the higher value of (n+l) where 'n' is azimuthal quantum number and 'l' is angular quantum number.

For 5p :

n = 5 and l = 2

(n + l) = 5 + 2 = 7

For 5d :

n = 5 and l = 3

(n + l) = 5 + 3 = 8

For 5f :

n = 5 and l = 4

(n + l) = 5 + 4 = 9

For 6s :

n = 6 and l = 1

(n + l) = 6 + 1 = 7

For 6p :

n = 6 and l = 2

(n + l) = 6 + 2 = 8

Hence, the orbital that has the highest energy is, 5f
