Excited State Configurations
Excited state configurations occur when electrons in an atom gain energy and jump to higher orbitals. This change alters the usual arrangement of electrons in the atom. For iridium, these states help explain its chemical and physical behavior.
Electrons do not always stay in their lowest energy positions. In excited states, some electrons move to orbitals that are normally empty or partially filled. This movement changes the electron configuration temporarily.
What Causes Excited State Configurations In Iridium?
Energy from light or heat can push iridium's electrons into excited states. This energy makes electrons jump from lower to higher orbitals. The atom becomes unstable and wants to return to the ground state.
Examples Of Excited State Configurations
In iridium, an electron from the 5d or 6s orbitals can move to a higher orbital like 6p. This shift creates an excited state configuration. These are different from the atom’s normal electron setup.
