Which electronic configuration must represent an atom in an excited st...
Excited State Electronic Configuration
An atom in an excited state has at least one electron in a higher energy level than the ground state electronic configuration.
Explanation of Options
a) 1s2, 2s2 2p1 - This is the ground state electronic configuration of carbon. It has all its electrons in the lowest possible energy levels.
b) 1s2, 2s2 2p2 - This is also the ground state electronic configuration of oxygen.
c) 1s2, 2s2 2p2, 3s1 - This represents an excited state of aluminum. One of the electrons from the 3s orbital has been promoted to the 3p orbital.
d) 1s2, 2s2 2p5 - This is the ground state electronic configuration of fluorine.
Conclusion
The correct answer is option 'C' because it represents an atom in an excited state.
