What is the electron valence shell for c3h8?
The valence shell is the outter most shell that contains the most electrons. To find out how many valences there are you would mulitply the electrons. C3H8= (6)3 + (1)8=26 the outer valence shell will be 20.
How many electrons are supposed to be on the outter layer?
Depends on what element you are talking about.
