Boron, silicon, germanium, arsenic, antimony, and tellurium are commonly recognised as metalloids. Depending on the author, one or more from selenium, polonium, or astatine are sometimes added to the list. Boron sometimes is excluded, by itself, or with silicon.
Which Elements Are Metalloids?
The metalloids are a group of elements in the periodic table. They are located to the right of the post-transition metals and to the left of the non-metals. Metalloids have some properties in common with metals and some in common with non-metals.
The term is normally applied to a group of between six and nine elements (boron, silicon, germanium, arsenic, antimony, tellurium, and possibly bismuth, polonium, astatine) found near the center of the P-block or main block of the periodic table.
The elements which display properties of both metals and non-metals are classified as metalloids. In the Periodic Table, they separate metals from the non-metals. For eg. Silicon, Arsenic etc. webew7 and 63 more users found this answer helpful.
Metalloids are the elements which are having a combination of some properties of metals along with some properties of nonmetals. Their properties are intermediate between the properties of metals and nonmetals, they are also called semi-metals. Example: – Boron, Silicon, Germanium, etc.
1 : an element intermediate in properties between the typical metals and nonmetals. 2 : a nonmetal that can combine with a metal to form an alloy.
The elements which are found in the step-like line between metals and nonmetals of the periodic table are known as the metalloids. They are: antimony (Sb), germanium (Ge), silicon (Si), arsenic (As), tellurium (Te), polonium (Po), boron (B), and astatine (At).
The six metalloids are silicon, boron, germanium, arsenic, antimony, and tellurium.
The elements which show some properties of metal and some properties of non-metal are called semi-metals or metalloids. Example — Boron Silicon Germanium Arsenic.
In the modern periodic table there are six metalloids which are boron , silicon , germanium , arsenic , antimony and tellurium .
