The maximum number of electrons at the 5th and 6th energy levels are 50 and 72, respectively. This is calculated using the formula 2n^2, where 'n' represents the principal quantum number, or energy level. For the 5th level (n=5), it translates to 2(5^2) = 50 electrons, and for the 6th level (n=6), it results in 2(6^2) = 72 electrons. These values reflect the full capacity of subshells within each energy level.
FAQs & Answers
- How is the maximum number of electrons in an energy level calculated? The maximum number of electrons in an energy level is calculated using the formula 2n², where n is the principal quantum number representing the energy level.
- Why does the 6th energy level hold more electrons than the 5th? Because the capacity depends on 2n², as n increases, the number of electrons that an energy level can hold increases; for n=6, it is 72 electrons, which is more than the 50 electrons at n=5.
- What does the principal quantum number represent? The principal quantum number, denoted as n, indicates the main energy level or shell in which electrons reside in an atom.
