Are there 7 metalloids?
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.

Why do metalloids exist?
They fall between metals and nonmetals in their ability to conduct heat, and if they can conduct electricity, they usually can do so only at higher temperatures. Metalloids that can conduct electricity at higher temperatures are called semiconductors. It is used to make the tiny electric circuits in computer chips.
Is Silver rarer than gold?
Most studies agree gold is overall the more rare of the two metals; however, above ground silver is actually more rare than gold. Estimates report gold is 5-7x more abundant above ground than silver. Beneath the surface, silver is approximately 19x more abundant than gold.
Is Gold more valuable than diamond?
Since the value of gold is predictable and stable, gold has more value than diamonds. Natural diamonds are created when carbon is subjected to extreme pressure over millions of years. Only a highly prized diamond, like a very large stone or an unusual color, will hold its value or become more valuable over time.
Should I buy diamond or gold?
When markets are in a recessionary period, gold is often sold to offset losses. Due to the fact that gold is the most popular precious metal that cannot be synthetically produced – unlike diamonds – there is transparency when one buys gold in the open market. One could simply not go wrong with gold.
