Silicon and germanium semiconductors are most commonly used in memory and logic chips.
The three main categories of elements on the periodic table are metals, metalloids, and nonmetals.
The solvents used to dissolve plating metals often were highly toxic. Cyanide, for example, was a commonly used solvent.
Rare earth metals are widely used for technological advancement in the 21st technology. It commonly used for car batteries, car engine and car frames. Aside from that, rare metals are also present in cellphones and some other gadgets and devices.
There are many answers for this question. I am basing it from how these metals are used by humans. Steel is a major building material, it is extremely strong and sturdy, welded easily, and the most common metal used by humans today. Aluminum is a very light, medium-soft metal, commonly used in car bumpers, especially in the "Mini Cooper." Gold is both very valuable for its looks, but for its uses too. Gold is commonly used in jewelry, but is even more commonly now days used in high grade electronics. The electric conductivity is extremely useful in these electronics. Copper is a common metal used in heaters due to its amazingly powerful heat conductivity. Zinc is commonly used to cover the corrosive properties and ultimately protect steels and other metals from corrosion. Iron is almost as hard as steel, but not as malleable and tough as it. It is commonly used for building anvils.
The most commonly forged metals are carbon steel and alloy steel.
tin and lead
The two most common metals used to make knives are steel and iron.
zinc chromium tin
Radioactive metals like uranium, titanium which emit alpha, beta & gamma rays.
Silicon and germanium semiconductors are most commonly used in memory and logic chips.
Copper and Aluminium
The three main categories of elements on the periodic table are metals, metalloids, and nonmetals.
Alkali and alkaline earth metals are too chemically reactive to stay in metallic form.
what are three types of timber that are used for woodturning
Gold silver. Steel
The solvents used to dissolve plating metals often were highly toxic. Cyanide, for example, was a commonly used solvent.
