Concept:When an atom absorbs energy, an electron jumps from its ground-state orbital to a higher-energy orbital within the same shell.
Explanation:Carbon has atomic number
6, so its ground-state configuration is:
1s22s22px12py1In the excited state, one of the
2s electrons is promoted to the empty
2pz orbital.
Therefore, the excited-state configuration becomes:
1s22s12px12py12pz1This configuration still has a total of
6 electrons, but one electron has moved to a higher-energy
2p orbital.
The option that matches this is option C.
Answer:C.
1s22s12px12py12pz1
