Hydrogen, symbol H, atomic number 1, is a non metal.
Magnesium is classified as a metal.
It's an ionic substance. Well it's true that ionic substances are usually composed of a metal + a non-metal (or a polyatomic anion), but ionic substances can also be composed of a polyatomic cation + a non-metal (or a polyatomic anion). anion: negatively charged ion cation: positively charged ion
Non metal
Calcium Chloride is an ionic compound. You see, for a substance to be classified as either a non-metal or a metal, it has to be in elemental form. Calcium Chloride is a compound, so you can't say whether it is a non-metal or a metal. However, of the elements that make up this compound, Calcium is a metal and Chlorine is a non-metal.
Original answer: yes-it is the strongest substance on earthYes, diamond is the strongest Natural substance on earth, but it is not nearly the strongest substance of all, and diamond is a mineral... not a metal... there are other ores such as titanium and tungsten that can be strengthened to become thousands of times stronger than diamond.

Calcium is not a non-metal, it is an alkaline earth metal.
An ionic substance, or a salt
it is a alkaline earth metal
Holmium is a rare earth metal.
To find out whether a substance is a metal, its electrical conductivity, and the acid-base character of its oxides are researched.
Fluoride is neither, it is an ion that cannot exist on its own as a substance because it is electrically charged. Fluorine is a non-metal.
Lignite is a non-metallic substance.
