They do have their own names!
The Periodic Table is actually split up into far more groups then just the metals and non-metals.
The groups actually are as following:
The Alkali metals
The Alkaline earth metals
The Lanthanides
The Actinides
The transition metals
Other metals
(all of the above are collectively grouped as the metals.)
The Metaloids (these can neither be definitely grouped as metals or non-metals as they share properties of both.)
Other non-metals
The Halogens
The Noble gases
(these are collectively grouped as non-metals.)
The reason for the fact that the collective groups being known as just the metals and non-metals is most likely due to the fact that there are far more metals, so it is more likely that these were discovered and then named first.
There is no strong definition on what is a metal or non-metal, however, non-metals can generally be defined by having a negative valence whereas metals have a positive valence.
Some similarities of metals, nonmetals, and metalliods are that they all have a sound when hit, and all have a grayish like color.
No, carbon does not have properties of both metals and nonmetals. It is a nonmetal and has properties such as being a poor conductor of electricity and having a low melting and boiling point. Carbon does not exhibit metallic properties like luster, malleability, and the ability to conduct electricity like metals do.
An alloy like steel, a homogenous mixture of metals (and some nonmetals as well).
True. Metalloids look like metals but are brittle and are not good conductors.
Metal like Sodium Chloride. Sodium is the Metal and Chloride is the Nonmetal.
I like trains:d

The three classes of elements are metals, nonmetals, and metalloids.
nonmetals look like metals but are dull and brittle .
semimetals have some characteristics of metals nonmetals and have their own section on the table.

No, some like Sulfur and Silicon are Nonmetals and Metalloids respectively.

Metal like Sodium Chloride. Sodium is the Metal and Chloride is the Nonmetal.
Look around your house and you'll find that most metal objects share common appearances. Generally, metals are lustrous (shiny), fairly hard, ductile (they can be stretched), and malleable (they bend instead of break like nonmetals do).
