Earth has a metallic core too. Besides mars is smaller than earth which means it would probably have a smaller core.

If the metallic core takes up a smaller proportion of the planetary mass then it can certainly have a metallic core and still have a mean density less than that of Earth.

Mars has a metallic core, it's just smaller. The density of Mars is less because unlike Terra(Earth) is has no magnetic field. It also has no plant life and very little atmosphere.

Who says that Mars does or should have a metallic core?
Could be ice for all we know. :)

Just because Mars is less dense than Earth is no reason for it NOT to have an iron core. I don't follow your logic.
