Is silicon a metal?
For this reason, silicon is known as a chemical analogue to carbon. But unlike carbon, silicon a metalloid — in fact, it’s the most common metalloid on earth. “Metalloid” is a term applied to elements that are better conductors of electron flow — electricity — than nonmetals, but not as good as metals.

Why Valency of chromium is 3?
Valency is the combining capacity of an element. It is equal to the number hydrogen atoms with which one atom of a particular element combines to form its normal hydride. Hence, the valencies of chromium can be taken as 2 and 3, as in the case of iron, which is also a transition metal……
What is the difference between Chrome and chromium?
Chromium is an open-source browser project that forms the basis for the Chrome web browser. The biggest difference between the two browsers is that, while Chrome is based on Chromium, Google also adds a number of proprietary features to Chrome like automatic updates and support for additional video formats.
