Question

The elements silicon, germanium and arsenic are called metalloids :
A.True
B.False

Answer 1

Hint:In the given question firstly we have to get what exactly is the metalloid abou which we talk about. The metalloid is a kind of the element that can neither be given a category of metal or non-metal. Therefore we can say that they are a blend of their properties and there are six of them namely, boron, silicon, germanium, arsenic, antimony, and tellurium.

Complete step by step answer:
There are 3 elements given in the given problem statement. They are :
First element is the Silicon
Second element is the Germanium
 Third element is the Arsenic
Now after all these three elements we can tell that they are found in the group $14$ and $15$ of the modern day periodic table. This place is just to the side of the non-metal section of the table.
Now for the case of the metalloids we need to know what exactly are the metalloids.
The Metalloid can be classified as a type of a chemically found or obtained element which has a preponderance or in simple words the blend or simultaneous acquirance of the properties in between. Basically they are that elements that are a great blend or mixture of properties of, those of metals and nonmetals. There cannot be a standard definition of a metalloid as a standard case nor complete agreement for the case of which of the elements appropriately classified under this category. Still we can say that despite the lack of specificity, the term remains widely and extensively in use in the literature of chemistry.
The six commonly recognised metalloids are boron, silicon, germanium, arsenic, antimony, and tellurium.
By this explanation we can easily say that the correct option is the True.

Note:
Typical metalloids are prone to have a metallic appearance, but they are also brittle and only fair conductors of electricity which separates them for the case. Chemically they are found to behave mostly as nonmetals. They have a serious tendency to form alloys with metals. Most of their other physical properties and chemical properties are intermediate in nature.
