Is aluminum a pure element?

Aluminum is the third most abundant element in the Earth’s crust, falling behind oxygen and silicon. … Aluminum occurs naturally only in compounds, never as a pure metal. Removing aluminum from its compounds is quite difficult. An inexpensive method for producing pure aluminum was not developed until 1886.

Why are some metals not shiny?

Metals are shiny because they have a lot of free (i.e. delocalized) electrons that form a cloud of highly mobile negatively charged electrons on and beneath the smooth metal surface in the ideal case. … So, there are no regions within the metal that are more negatively charged than the other.

Is Zinc shiny or dull?
