The electronic configuration 1s2 2s2 2p6 3s1 3p1 describe excited state of Mg+.
Explanation:
As we know,
The atomic number of Mg = 12
Electronic configuration = 1s2 2s2 2p6 3s1 3p1
Since it has 12 electrons, so
∵ Mg → Mg+
1 2 1 11 1
Thus, it displays an excited state of Mg+.
Hence, Option A is the correct answer.
