Question

What are metalloids?

Answer 1

Hint : Let us get some idea about metalloids. Metalloids are a small group of elements that can be found in the periodic table of elements along the zigzag line that separates metals from non-metals, which runs from boron to aluminium and ends at the boundary of polonium and astatine.

Complete Step By Step Answer:
The elements that are considered metalloids are as follows:
Boron $\left( B \right)$
Silicone $\left( {Si} \right)$
Germanium $\left( {Ge} \right)$
Arsenic $\left( {As} \right)$
Tellurium $\left( {Te} \right)$
Polonium $\left( {Po} \right)$
Antimony $\left( {Sb} \right)$
From the ${13^{th}}$ to the ${16^{th}}$ group of the periodic table, these seven elements were categorised as metalloids.
Astatine was expected to be classified as a non-metal or a metalloid. Metal creation has also been predicted.
Metalloids have properties that are halfway between those of metals and those of non-metals. They have difficult-to-describe characteristics.
Boron $\left( B \right):$
Boron is used in fireworks because it has the property of becoming green when burned. It's one of the most dangerous metalloids around.
It can be used as a cleaning agent and comes in the form of boric acid.
Boron can be utilised as a semi-natural pest control agent when used in tiny amounts.
Silicone $\left( {Si} \right):$
Silicon is used in computer chips because it is a semiconductor.
Silicon in silicones is a waterproof sealant that can be used on roofs and around water pipes.
Germanium $\left( {Ge} \right):$
In the semiconductor industry, germanium is utilised to improve conductive characteristics.
Germanium is used in fluorescent lamps and infrared detectors.
Arsenic $\left( {As} \right):$
Arsenic can be utilised as a semiconductor when combined with gallium and is used in LEDs.
Because of its toxicity, arsenic can be employed as a pesticide and to preserve wood.
Arsenic was utilised in the production of lead alloys for bullets.
Antimony $\left( {Sb} \right):$
Paints and ceramic enamels contain antimony as one of the components.
Egyptians utilised antimony as a cosmetic in ancient times.
Tellurium $\left( {Te} \right):$
To prevent thermal shocks, it is utilised in the production of cast iron and ceramics.
Polonium $\left( {Po} \right):$
Polonium is the rarest element on the planet, and it is highly radioactive and hazardous in nature.

Note :
Let us know more about metalloids. Metalloids are good semiconductors. Metalloid reactivity is determined by the properties of the elements with which they react. Metals and non-metals differ in electronegativity and ionisation energy.
