Question
How many valence electrons are elements trying to reach in their outer shells?
- 1
- 2
- 5
- 8
Hint:
Noble gases have 8 electrons in their outermost shell.
The correct answer is: 8
- The electrons in the outermost shell are called valence electrons.
- Noble gases have 8 electrons in their outermost shell, the most stable electronic configuration.
- 8 valence electrons elements are trying to reach in their outer shells.
