Final answer:The electron configurations that represent atoms in an excited state are options (b) 1s 2 2s 2 2p 5 3s 2 and (c) 1s 2 2s 2 2p 6 3s 1.Explanation:An atom is in anexcited statewhen one or more electrons are elevated to a higher energy level than the ground state. In its ground state, an atom organizes its electrons in the lowest energy arrangement possible, which means filling the lower energy levels before the higher ones.Examining the givenelectron configurationsforneutral atoms, we see:1s 2 2s 2 2p 5 - Fluorine (ground state)1s 2 2s 2 2p 5 3s 2 - Sulfur (excited state)1s 2 2s 2 2p 6 3s 1 - Sodium (excited state)1s 2 2s 2 2p 6 3s 2 3p 2 - Silicon (ground state)1s 2 2s 2 2p 6 3s 2 3p - Aluminum (ground state)So, options (b) 1s 2 2s 2 2p 5 3s 2 and (c) 1s 2 2s 2 2p 6 3s 1 represent atoms in excited states.Learn more about Excited State Atoms here:brainly.com/question/1968924#SPJ4...
