Because they are metalloids, which have some of the properties of metals and some of the properties of nonmetals, except for aluminum, which is not a metalloid.
Because this answer isn't true I tell you why later
Most of the elements touching the stair-step line on the Periodic Table are what we call "metalloids" or semi-conductors. Elements to the right of the stair step line are nonmetals and have properties such as brittle, and non-conductive. The elements to the left of the stair step line are metals, they are ductile and malleable, and are great conductors. The semi-conductors or metalloids touching the stair-step line have properties in between metals and nonmetals. Silicon is a great example. Silicon conducts electricity, but only under special circumstances.
The elements in the staircase are known as metalloids. Metalloids are special because their properties are in-between those of metals and solid nonmetals. They are electrical semiconductors.
The staircase separates metals from non-metals. The elements on the stair case is metalloids, the metals to the left of the stairs are metals and the elements to the right of the stairs are non-metals.
Elements on the left side are metals and those on the right side are nonmetals.
The elements on the stair case are called metalloids.
The 3 major divisions on the periodic table are metals(metalloids), non-metals, and gases.
this is the line that seperates metals and non-metals. those on the left are metals and those on the right are non-metals.
They are metalloids.
They tend to be non-metals.
Metals are found on the left hand side on the Periodic Table (towards the left of the "staircase". The "staircase" line divides elements into metals and non-metals. Elements to the right of the "staircase" are the non-metals. However, those close to the staircase have both metallic and non-metallic properties and hence are called metalliods.

On the Periodic Table there is a zigzag line (staircase) running along group 13 to group 16. Metalloids are the elements along the staircase. The six elements commonly recognized as metalloids are boron, silicon, germanium, arsenic, antimony and tellurium.
