Answer
8
Explanation
The second shell can hold a maximum of 8 electrons according to the 2n² rule, where n is the shell level.
Common mistake
Misrepresenting Electron Shells
Students often incorrectly draw the electron shell diagrams for elements, placing too many electrons in the outer shell or not following the 2,8,8 rule for higher energy levels.
Ensure that the first shell holds a maximum of 2 electrons, the second shell holds up to 8, and the third shell also holds up to 8 for the first 20 elements.
