Question

Why the silicon and germanium come under the category of metalloid?​

Answer 1

Answer:

Explanation:

Silicon is a metalloid because it has luster, but is brittle.Silicon has 4 electrons in its outer orbitals and to attain stable state it can DONATE all its electrons like a METAL or it can ACCEPT 4 electrons like NON METALS!! ,it shows both the properties of a metal and a non-metal . So,it is called a metalloid or a semi-metal.

As a metalloid, germanium has both metal and non-metal qualities. It also is a semiconductor, which means it has electrical conductivity between an insulator and a conductor. ... Germanium does not react with oxygen at room temperatures, but will form germanium dioxide at higher temperatures.

Answer 2

Answer:

METALLOID ARE THE SUBSTANCES WHICH SHOW BOTH THE CHARACTEISTICS OF METALS AND NON- METALS. SO CLEARLY , SILICON AND GERMANIUM ARE METALLOIDS BECAUSE THEY SHOW THE CHARACTERISTICS OF BOTH METALS AND NON - METALS.
