Source sentences:
text: The noble gases have the same problem—there is no room for any more electrons in their outer shells.
text: All noble gases have the maximum number of electrons possible in their outer shell (2 for Helium, 8 for all others), making them stable.
text: Chemically, they are very stable because they have the maximum number of valence electrons their outer shell can hold, causing them to rarely react with other elements.
text: Based on the fact that neon is a noble gas, we can determine that its outer shell is full with eight electrons, and will therefore not likely react with other chemicals.
