Energy Level and Transition of Electrons - Brilliant
Web5 de set. de 2024 · The highest energy level number (1 through 7) for the electrons in an atom corresponds to the period (or row) in the periodic table to which that atom belongs. Because there are 7 periods in the table, there are 7 energy levels. For example, hydrogen (H) is in the first period, so it has only one energy level. WebFor any element in the periodic table, the number gives the n value of the highest principal energy level containing electrons. For main group elements only, the number is always equal to the number of valence electrons.
