It is the transition metals, which have the characteristic of metals and nonmetals. For instance, silicon. These materials are particularly useful in the semiconductor industry.

___________________________________________________THE RIGHT ANSWER:Elements that lie close to the "stair-step" line are called metalloids. Sometimes known as semimetals

huh okkay

A bit more information:

The stairstep line divides the metals (on the left) from the non-metals (on the right). With the exception of aluminum, the elements sitting on or holding up the line are metalloids, which have properties that are a combination of those of metals and non-metals. Properties include luster, the ability to be drawn into wires and hammered thin, (ductile and malleable), and conducting heat and electricity for metals. Brittleness, dull or matte appearance, and insulating are characteristics for non-metals.

The stair step is the zig zag pattern of elements between the metals and nonmetals. The elements in the step are metalloids. Examples of elements in the stair step are silicon germanium and antimony.

They're called the metalloids. They have some properties of metals and some properties of non-metals. Silicon is perhaps the best known and most common.

It tells me that the elements were well organized in good order before the final peridoci table was actually aproved.

It divides the metals from the nonmetals. Also all of the elements, except aluminum, that share 2 sides with the line are metalloids.
