Compare the physical properties of metals, non-metals, metalloids, and noble gases, and describe where in the periodic table each of these kinds of elements is located.

The metals are shiny. They are solid at room temperature (except mercury) are malleable and ductile. They are good conductors of heat and electricity but as the temperature increases, their electrical conductivity decreases. The metals are to the left and center of the periodic table. The metal elements are from group 1 (except hydrogen) to 12, in addition to others that form a broken line in the periodic table of group 13 to 16

Nonmetals do not shine like metals. They are usually brittle, some hard and others soft. They are bad conductors of heat and electricity. They are located to the right in the periodic table above the broken line.

Metalloids have an intermediate behavior between metals and nonmetals. They can be bright or opaque. They change shape easily. They are better conductors of heat and electricity than nonmetals, but not as much as metals. They are semiconductors. When the temperature is increased, its electrical conductivity increases. Within the periodic table the metalloids are in a diagonal line.

The noble gases are a group of non-metallic chemical elements that, under normal conditions of pressure and temperature, are monoatomic, odorless, colorless gases. The noble gases have very weak intermolecular forces and, therefore, have very low melting and boiling points. They are placed in group 18 of the periodic table.
