Why is mercury not combustible?

Because the chemistry gods were smiling on us the day they came up with the flammable metals. Mercury vapor is dangerous enough as it is; can you imagine how bad mercury smoke would be?

Okay, here's the real reason - and it's also the reason mercury is liquid at room temperature. Combustion is an exothermic oxidation process. Mercury's outer shell makes it very much like a noble gas. This trait does two things for us. First, it makes it noncombustible. The other is it makes it impossible for mercury atoms to bond into a solid mass.
