The maximum number of electrons that can be accommodated in the outermost orbit is ________.
8
While a shell with principal quantum number n can theoretically hold a maximum of 2n^2 electrons (e.g., the second shell, n=2, can hold 2 × 2^2 = 8 electrons; the third shell, n=3, can hold 2 × 3^2 = 18 electrons), the outermost shell of an atom typically becomes stable when it contains 8 electrons. Therefore, the maximum number of electrons that can be accommodated in the outermost orbit to achieve stability for most atoms is 8.
