Oxides : Copper, aluminium, zinc, tin, iron, etc., occur as oxides.
Sulphides : Silver, copper, zinc, mercury, lead, iron, etc., occur as sulphides.
Carbonates : Sodium, copper, calcium, magnesium, zinc, lead, iron, etc., occur as carbonates.
Sulphates : Sodium, calcium, magnesium, lead, etc., occur as sulphates.
All of the metals that we find on Earth originated billions of years ago. Inside the ultra-hot environment of the stars, simple hydrogen and helium atoms fused together to create heavier elements.

How many ways of making metals
Iron ore is smelted in a blast furnace: superheated air – up to a “bang” of 2200°F – rushes towards the furnace, causing it to burn much hotter than it otherwise would.
Pure steel is very vulnerable, so it can rust.
Rubies, emeralds and sapphires contain a key chemical component: aluminum.
What is the vast majority of platinum ultra-rare content for?

Why are metals good conductors of electricity
Why are metals conductors of electricity and conductors of cold? Metals form bonds, in the metallic sense, this means that many electrons are delocalized.
Their delocalized electrons may well electrically charge our own metal.
Their delocalized electrons can transmit arctic energy.
The atoms of the material form a specific matrix that allows the outer electrons to move freely through the metal.

What are the most common metals
Oxygen is the favorite element of the earth’s crust
Hydrogen is the most abundant element in the known universe, but only makes up the 10 most abundant elements in the Earth’s core crust.
Aluminum is the most abundant metal in the earth’s crust.
How can you identify metals
To check for aluminum and magnesium, follow these steps: Rinse with clean water and leave for 5 minutes.
Apply one to two drops of 20% sodium hydroxide solution (NaOH) to the area to be cleaned.
Clean a large metal surface. Black: Al + Cu (Copper), Ni (Nickel) or Zn (Zinc) Grey/Brown: Al + Si (Silicon, more than 2%) White: Pure aluminum No color change: (Mg) Magnesium

How is metal formed in nature
More often, metals may be mixed with rocks and minerals in nature. When a metal is mixed with a rock other than minerals, it is called an ore. Before going for metals, you must remove that company from the ore. This process can be called fusion.
Where are metal made from
Metals are minerals, such as flat iron or lead, found underground in the form of rocks. They are separated from the rocks you see with the help of heat. Metals are extremely useful materials.
What makes a metal a metal
Metal, a class of materials characterized simply by high electrical and thermal conductivity, as well as ductility, ductility and high light reflectance. About three-quarters of all known chemical elements become metals.
What happens when copper powder is heated in air * blue colored copper sulphate is formed black colored copper oxide is formed blue colored copper nitrate is formed pale green copper carbonate is formed
While copper powder can be described as being heated in a porcelain dish, the surface of copper powder is usually coated with a black substance because copper oxide is usually formed by surface corrosion. The black color is due to the formation of this ornithologist (II) because copper appears as an oxide upon contact with this particular air.
What happens when dilute sulphuric acid is poured on a copper plate copper sulphate formed copper chloride formed hydrogen sulphide formed copper sulphide formed
Answer: Answer: Copper does not react like dilute acid with sulfuric acid. Therefore, when dilute sulfuric acid is poured onto a plate of a water pipe, no reaction occurs.
