How many electrons are in the outer shell of helium compared to other noble gases?
Answer
Helium has two electrons in its outer shell, while the other noble gases, such as neon and argon, have eight electrons in their outer shells.
Explanation
This answer is strong because it directly addresses the question by clearly stating the number of electrons in helium's outer shell and contrasting it with other noble gases. The question tests the student's understanding of the electron arrangement in noble gases.
Common mistake
Helium's Electron Configuration Mistake
Students often state that helium has eight electrons in its outer shell, similar to other noble gases.
Remember that helium has only two electrons in its outer shell, while all other noble gases have eight.
