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
The iron ore is likely smelted in a blast furnace: superheated air – up to 2200°F – is “blown” into their furnace, causing it to burn much softer than would otherwise be possible.
Clean contents are highly susceptible to corrosion.
A key chemical component commonly found in rubies and sapphires: aluminum.

Why are metals good conductors of electricity
Why are metals both electrical and thermal conductors? Metals form metallic bonds, that is, the electrons are delocalized.
Their delocalized electrons can carry an electrical charge through the metal.
Their delocalized electrons are said to carry thermal energy.
The clothing atoms form a matrix in which the outer electrons are free to move due to the chromium effect.

What are the most common metals
Most of the oxygen is in the earth’s crust
Hydrogen is the most abundant element in the so-called universe, but makes it only the tenth most abundant element in the earth’s 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 wait 5 minutes.
Apply one to two drops of a 20% caustic soda (NaOH) solution to a clean surface.
Clean the area and the metal itself Black: Al + Cu (copper), Ni (nickel) or Zn (zinc) Grey/brown: AL + Si (silicon, more than 2%) White: pure aluminum No color change: (Mg ) mineral magnesium

How does metal naturally form
Simply put, if you dig and/or collect rocks in any given soil, you will find metals very quickly because that is where they naturally occur. Metals usually form compounds, also called minerals. These are usually natural solids composed of chemicals and crystalline structures. They are inorganic, which means they do not live.
Does the earth produce metals
Yes, many metals are produced in Fischer decay cycles, heavier radioactive metals as the earth’s core gets lighter. Metals are produced chemically in different ways, unfortunately there are no more atoms of stainless steel than there were originally.
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
When a portion of the heated copper powder is placed in one porcelain bowl, the surface of the copper powder is covered with black color information due to the formation of carbon monoxide by surface oxidation. The dark gray color is due to the nature of this copper oxide, so the copper comes into contact with 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 with dilute sulfuric acid. Therefore, when a dilute acid containing sulfur is poured onto a copper plate, no reaction occurs.
Which movement causes day and night on Earth rotation of Earth revolution of Earth around the sun Earth’s elliptical orbit in space moon’s orbit around Earth
earth rotation. The solar system is not only the actual collection of planets, moons, but also other bodies around the sun. Each planet rotates around its own axis. The rotation of the Earth on its axis causes a change of day and night.
