Select all the statements that correctly describe the role of valence electrons in chemical reactivity:

- Filled valence s and p sublevels give exceptional stability to any atom or ion.
- Noble gases are highly reactive because their valence s and p sublevels are full.
- Valence electrons are the electrons that participate in chemical reactions because they are the farthest from the nucleus.
- The number of valence electrons lost or gained to adopt a noble gas configuration governs what ions are formed by main-group elements.
- Ions with filled valence s and p sublevels are highly reactive.
