The highest occupied electron shell is called the valence shell, and the electrons occupying this shell are called valence electrons. The chemical properties of the elements reflect their electron configurations. For example, helium, neon and argon are exceptionally stable and unreactive monoatomic gases.
OCTET RULE. The atoms that participate in covalent bonding share electrons in a way that enables them to acquire a stable. electronic configuration, or full valence shell. This means that they want to acquire the electronic configuration. of the noble gas of their row. Obviously the name of this rule is a misnomer.
