what element has valence electrons on the third energy level?
What in the world are you talking about? A pressure cooker comes with it's own lid and it locks into placeYou cannot use another type of lidnever even heard of anyone thinking they could in all of my years.
putting the glass on the stove would subject it to higher heat If it is in the pressure cooker, the highest temp it would be subjected to would be 246 F, since it is not in the direct heat.
3rd energy level meaning 3rd P.E.L., i assumingjust go down to the 3rd period of the periodic table and all the elements there will have valence electronsSodium (Na), Magnesium (Mg), Aluminum (Al), Silicon (Si), Phosphorus (P), Sulfur (S), Chlorine (Cl), and Argon (Ar)Argon is a noble gas that has an octet (8 valence electrons), so it will not share it's electrons with anymore, it will never give up any electrons either.
