Question

While electronic filling in orbitals, the orbital (energy level) coming after 5p is:

• A. 5s
• B. 6s
• C. 4s
• D. 4p

Answer 1

The correct option is B 6s

Explanation:

Since electron filling is done from lower to higher energy level as per the order ---

1s<2s<2p<3s<3p<4s<3d<4p<5s<4d<5p<6s<4f<5d<6p<7s...

So, as per the rule the orbital coming after 5p is 6s

S0, (B) option is correct
