Consider these two electron configurations for neutral atoms l and m. l - 1s22s22p63s2 m - 1s22s22p63s13p1 what is the difference between atom l and atom m? one of the 2p electrons in l has jumped to an excited state one of the 3p electrons in l has jumped down to a lower energy state one of the 3s electrons in m has jumped to an excited state one of the 3p electrons in m has jumped down to a lower energy state
