what are metalloids??

Metalloids

The elements that border the stair-stepped line are classified as metalloids. The metalloids, or semimetals, have properties that are somewhat of a cross between metals and nonmetals.

Metalloids tend to be economically important because of their unique conductivity properties (they only partially conduct electricity), which make them valuable in the semiconductor and computer chip industry.

Metalloid react with acid and base both to form salt. For example Aluminum is a a metalloid which react with base and acid both

Those elements which behave as metal and non-metal both are called metalloids. For example: Boron, Silicon, Germanium, Arsenic, Antimony, etc.

A metalloid is a chemical element with properties that are in-between or a mixture of those of metals and nonmetals, and which is considered to be difficult to classify unambiguously as either a metal or a nonmetal.example- boron, silicon, germanium, arsenic, antimony, tellurium, polonium

 Metalliods are in the peroidic table of elements, but they have different places. Metalloids are in between metals and non-metals. It starts with the letter B which is for Boron and it goes down diagonaly. If you look up the table of element then it would tell you by its color and their would be a line (if possible) because they are gases too.
