Question

which subshell among the following has the highest energy?(2p,4s,3d,3p)​

Answer 1

Answer:

3d

Explanation:

according to n+l rule it has highest value

Answer 2

ENERGY LEVEL OF SUBSHELL -

• The energy level is determined by the (n + l) value.
• The subshell are enumerated as -

s - 0 (lowest energy shell)

p - 1

d - 2

f - 3

• In the given subshell the energy is determined by -

2p = 2 + 1 = 3

4s = 4 + 0 = 4

3d = 3 + 2 = 5

3p = 3 + 1 = 4

• The highest value of (n + l) is of 3d so the shell will have the highest energy.
