Which of the following electron configurations correspond to an atom with an electron in an excited state? (a) [ne]3s23p4 (b) [ne]3s13p6 (c) [he]2s22p3 (d) [kr]5s24d85p1 (e) [ar]4s23d8

The correct answer is option (B) [Ne]3s¹3p⁶.

The electron configuration of Cl is [Ne]3s²3p⁵ in the ground state.

The electron configuration of Cl is [Ne]3s¹3p⁶ in the excited state.

In the excited state one electron from the 2s orbital jumps to the 2p orbital. As a result the 2p orbital becomes completely filled with 6 electrons and the 2s orbital is partially filled with only 1 electron. To be completely filled a p and a s orbital can have a maximum of 6 and 2 electrons respectively.

Thus [Ne]3s¹3p⁶ electron configuration correspond to an atom with an electron in an excited state.

it should be all of them because it asks if you included all of those in your answer

explanation:

answer: they produce more slow than unicellular organisms.
