Can hydrogen be a metal?

Hydrogen is not considered a metal, even though it does exist in Group I (alkali metals) of the periodic table. Metallic hydrogen has been predicted at extremely high pressure (e.g., interior of Jupiter), under which compressed hydrogen atoms lose their electrons to delocalization ("sea of electrons").

Are Diamonds bullet proof?

It doesn't seem unreasonable to wonder whether diamonds are bulletproof, since diamond is the world's hardest natural material. Diamonds are not however bulletproof in general, as while they are hard, they are not particularly tough and their brittleness will cause them to shatter when struck by a bullet.

What can cut diamond?

Is Borazon harder than diamond?

A diamond ring. Scientists have calculated that wurtzite boron nitride and lonsdaleite (hexagonal diamond) both have greater indentation strengths than diamond.

Can you melt a diamond?

In the absence of oxygen, diamonds can be heated to much higher temperatures. Above the temperatures listed below, diamond crystals transform into graphite. The ultimate melting point of diamond is about 4,027° Celsius (7,280° Fahrenheit).

Is steel harder than diamond?

Are Diamonds Stronger than Steel? A diamond is smoother than steel since its molecules are held more tightly together. However, a diamond is not stronger than steel. Steel is also denser than diamonds because each molecule weighs much more than a carbon atom alone.
