The 6th energy level of an atom can hold up to 72 electrons. This capacity is determined by the formula 2n^2, where n is the principal quantum number or the energy level number. For the 6th level, calculating 2*(6^2) results in 72. This capacity is key in understanding the electron configuration of atoms, particularly for elements with higher atomic numbers in the periodic table.

FAQs & Answers

  1. What is the formula to calculate the maximum electrons in any energy level? The maximum number of electrons in an energy level is given by the formula 2n², where n is the principal quantum number representing the energy level.
  2. Why can the 6th energy level hold up to 72 electrons? Because according to 2n², for n=6, the calculation 2 × 6² equals 72 electrons, which defines the capacity based on quantum mechanics.
  3. How does the 6th energy level relate to electron configuration in heavy elements? The 6th energy level's capacity influences the arrangement of electrons in heavy elements with higher atomic numbers, affecting their chemical properties.
