Gold is heavenly, in every sense of the word. Most people don’t know this but, while we mine for gold here on earth, all of the gold that’s deposited in our planet was formed during the explosions of stars and collisions of asteroids, and eventually found its way to earthRead More →
Around 95 of the 118 elements in the periodic table are metals (or are likely to be such). Where do metals come from? Most pure metals, like aluminium, silver and copper, come from the Earth’s crust. They are found in ores – solid materials called minerals, usually occurring in rock,Read More →
Metals react with oxygen to form metal oxides. These metal oxides are basic in nature. Magnesium oxide dissolves in water to form magnesium hydroxide solution. … 3)During the rusting of iron,iron metal combines slowly with the oxygen of air in the presence of water to form a compound called ironRead More →
Silicon. Silicon is a typical metalloid (see Figure 1). It has luster like a metal, but is brittle like a nonmetal. Silicon is used extensively in computer chips and other electronics because its electrical conductivity is in between that of a metal and a nonmetal. Where are the main locationRead More →
Malleability For example, sulphur and phosphorus are solid non-metals which are not malleable, they cannot be beaten into thin sheets with a hammer. Are all metals malleable? All the metals are malleable and ductile with the exception of mercury (Hg) as it is in the liquid state and it’s stateRead More →
Not all metals are magnetic. Actually, it depends on what you mean by the word “magnetic”. There are four basic types of magnetism that a material can have: superconducting, diamagnetic, paramagnetic, and lastly ferromagnetic. … Lastly, ferromagnetic materials are strongly attracted to permanent magnets. Why are only some metals magnetic?Read More →
Where does metal come from, country wise? China is by far the biggest producer of metal. In the 2009 U.S. Geological Survey, China was shown to have produced 900 million tonnes of iron ore, with the next highest producer being Brazil with 380 million. How did metal get on earth?Read More →
Ferrous metals are metals that contain iron and steel. Non-ferrous metals are those metals that do not have iron or iron components. What metals contain iron? The word ‘ferrous’ comes from the Latin word ‘ferrum,’ which means ‘iron. ‘ Ferrous metals include steel, cast iron, and titanium, as well asRead More →
This video from the minds at Veritasium explains the science of “cold welding.” When two metals touch in space, they can fuse together without the need for an open flame. … Without oxygen in space, the oxide layer over the metals disappears. Just add a little bit of force andRead More →
Answer: Metals are malleable and give thin sheets after hammering whereas non-metals are brittle and give no sheets. Metals are ductile and can be drawn into wires whereas non-metals are non-ductile and can’t be drawn into wires. … Metals are good conductors of heat and electricity while non-metals are poorRead More →
