im learning this in science, the most direct answer is 8, the equation to figure this out is 2 times n times n where n is the energy level in this case, 2, so 2 times 2 times 2=8. but once you get to the 18th element (i believe it is potassium) and above this equation no longer applies, but the most number of electrons possible on the second shell is still 8, no matter what element

The number of electrons that can go into any given principal quantum number (shell) n is 2n2. So there are 8 electrons in the second shell, and 18 in the third.
