Electrons Can Sometimes Fill Orbitals in Manners That Defy Specified

question 32

Multiple Choice

Electrons can sometimes fill orbitals in manners that defy specified rules. If they do so, we say that the atom is in an excited state. Which of the following represents the excited state of an atom?

• A) 1s²2s²2p⁶3s²
• B) 1s²2s²2p⁶3s¹3p¹
• C) both 1s²2s²2p⁶3s² and 1s²2s²2p⁶3s¹3p¹
• D) neither 1s²2s²2p⁶3s² nor 1s²2s²2p⁶3s¹3p¹
