Question

How can I classify metalloids?

Answer 1

Metalloids are a very small group of elements found in a periodic table of elements. That distinguishes metals from non-metals. Its physical and chemical properties fall in between metal and the non metal.

Complete step by step answer:
Metalloids possess some characteristics of metals and some of non-metals, semi-conductive and are metallic lustre.
There are only seven classified elements:
Boron
Silicon
Germanium
Arsenic
Antimony
Tellurium
Polonium
To determine if an unknown element is a metalloid it can be done by checking characteristics of metals and nonmetals if that element contains both properties then it is a metalloid.
Metalloids are chemical elements whose physical and chemical properties fall in between the metal and the non metal. Metalloids have metallic appearances but they are usually brittle and only mediocre electricity conductors. Chemically behave as non-metals.
General Properties of metalloids
Metalloids Typically look like metals. However, these elements often behave like non-metals.
Physically, metalloids are brittle, somewhat shiny substances that are usually solid at ambient temp.
They have intermediate to strong electric conductivity.
Chemically metalloids act as non-metals.
They have ionization energies and electronegativities (intermediate).
Metalloids are known to form amphoteric acid.
They form metallic alloys.
Many of the physical and chemical properties are mostly intermediate.

Note: Silicon is one of the most important materials used to make electronics such as computers and mobile phones. Arsenic is known to be one of the most poisonous of the elements. Antimony and tellurium are primarily used in metal alloys.
