Metals

What is Metal?

In addition to hydrogen, elements that give up cation by discarding electrons are called metals. Metals are shiny, malleable, and elastic. Metals are conductors of heat and electricitySilver and copper are the best conductors of electricity. Titanium is called strategic metal.

The safest metal is lithium, the heaviest metal osmium, and the hardest metal chromium. Potassium is the most reactive metal and gold is the least reactive metal. Gold, mercury, silver, and platinum are excellent metals.

The sturdy metal Tngst not have. Cadmium is used as a Newton diluent in a nuclear reactorPalladium metal is used in the manufacture of aircraft.

Selenium metal is used in photoelectric cellsZinc phosphide is used as rat toxinLead arsenic is used in pill making. Plutonium is a heavy radioactive metal.

What is Alloy?

A mixture of two or more elements is called a metal. For example, ammo is made of potassium nitrate, sulfur, charcoal. Dynamite is an alloy.

What is Ore?

He mineral metals which can be easily expelled, ore called. Such as – bauxite, cryolite, alunite, hematite, magnetite, limonite, iron pyrite dolomite, gypsum, fluorspar, silicate, etc.

Carbonate ores are converted into pure oxides by filtration. Sulfide ores are converted into metal oxides by the filling process.

What is the nature of a metal oxide?

The oxides of metals are alkaline in nature but chromium oxide is a metal that is acidic in nature. Oxides of aluminum, zinc, and lead are amphoteric.

What is the source of recovery of metals?

The main source of recovery of metals is the earth’s crust, which contains 7% aluminum, 4% iron and 3% calcium.

What is Yashvlepan?

To keep iron and steel safe from corrosion, a thin layer of zinc is added to them, which is called Yashvalepan.

What is a mineral?

Naturally found elements or compounds in the earth’s crust are called minerals.

What is Metallurgy?

The various processes involved in the extraction and refining of metals from ore are called metallurgy.

What is gangue?

The impure substance found in the ore is called gangue.

What is the flux?

Flux mixed to remove gang found in ore is called flux.

What is a clinker?

A substance consisting of gang and flux is called slag.

What is Calcination?

By heating the metal ore below its freezing point, the volatile impurities found in the ore are removed, which is called disinfection.
