Just as with your traditional 401k, you contribute pretax dollars to a traditional IRA (as I discuss further, you can only contribute pretax dollars up to certain income levels) and then benefit from tax-deferred growth and distributions.emember that contribution limits apply to the total of your contributions to all of your retirement accounts, either IRA or 401k. Note that the chart below includes the Roth option â which as of 2006 has been available for 401ks as well as IRAs.
Define excited state: a state of a physical system (such as an atomic nucleus, an atom, or a molecule) that is higher in energy than the ground state a state of a physical system (such as an atomic nucleus, an atom, or a molecule) that is higher in energy than the ground stateâ¦
Principal Quantum Level n = 1 is closest to the nucleus of the atom and of lowest energy. When the electron occupies the energy level of lowest energy the atom is said to be in its ground state. An atom can have only one ground state.If the electron occupies one of the higher energy levels then the atom is in an excited state. An atom has many excited states.ere's what happens... When a gaseous hydrogen atom in its ground state is excited by an input of energy, its electron is 'promoted' from the lowest energy level to one of higher energy. The atom does not remain excited but re-emits energy as electromagnetic radiation.
