Gimme two more!

See, it's chucklesome because the general rule is that atoms need eight valence electrons to be stable.

An atom with six valence electrons would need two more valence electrons to be stable. 

So they'd act like a guy yelling at the Subway worker for two more cookies.

Octet Rule Exceptions Tier List

The octet rule is a simple 'rule' that generally describes the behavior of elements in compounds: atoms are most stable when they have eight valence electrons.

But like every rule that humanity has come up with to describe the world around us, nature doesn't give even a little thought to following that rule. Nature does whatever nature does and our rules be damned.

As such, the octet rule is followed far more frequently that it is violated, but there certainly are compounds that don't follow the octet rule.
