Metals usually have 1,2 or 3 electrons in their valence shells. during a chemical reaction, metals have the more probability of loosing the valence electron(s) and hence becomes electropositive ions for which it is also know as a reducing agent.
What else can I help you with?
What type of chemical reaction is always involved in the extraction of metal from its ore?
The extraction of metal from its ore typically involves a reduction reaction, where the metal oxide in the ore is reduced to the elemental metal using a reducing agent such as carbon or hydrogen. This reduction reaction is necessary to separate the metal from the impurities in the ore.
How do you obtain aluminums element?
Aluminum is obtained through the extraction of bauxite ore, which is the primary source of aluminum. The extraction process involves refining bauxite into alumina through the Bayer process, followed by the electrolytic reduction of alumina to produce aluminum metal.
Is there any difference between extraction of metals and electrolysis?
Yes, there is a difference between the extraction of metals and electrolysis. Extraction of metals refers to the various methods used to obtain metals from their ores, which can include pyrometallurgy (using heat) and hydrometallurgy (using aqueous solutions). Electrolysis, on the other hand, is a specific technique often used in the extraction process, particularly for reactive metals, where an electric current is passed through a molten or dissolved electrolyte to separate the metal from its ions. While electrolysis is one method of extraction, not all metal extraction processes involve electrolysis.
What is the large vessel in which the extraction of iron by carbon reduction is carried out?
Blast Furnace
Why are such high temperatures needed and where does the the energy come from for extraction of metals?
High temperatures are needed in metal extraction processes, such as smelting, to facilitate the reduction of metal ores, allowing the metal to separate from oxygen and other impurities. This intense heat is typically generated from the combustion of fossil fuels or through electrical energy in processes like electrolysis. The energy helps to break the chemical bonds in the ore, enabling the transformation of raw materials into pure metals. Ultimately, the high temperatures ensure efficient extraction and processing of metals for industrial use.

What happens at the cathode in an electrolytic cell?
Reduction occurs at the cathode in an electrolytic cell.

What industries does not involve the extraction or production of raw materials or products from the earth?
Construction does not directly involve the extraction or production of raw materials or products from the Earth.
What is metal and nonmetal extraction?
A method for separation and recovery of metals and metal oxides from industrial minerals and waste materials Extraction from the metal ore involves reduction of the metal, and electrons can reduce any metal ion. metal ions + electrons metal atoms (reduction). non-metal ions - electrons non-metal atoms (oxidation). The electrodes are often made from graphite. The liquid which conducts electricity is called the electrolyte. The amount of electricity needed to produce a particular mass of metal (or non-metal) can be calculated. The negative electrode, called the cathode, will attract positively charged metal ions. The metal ions collect electrons from the cathode and are discharged as metal atoms. The positive electrode, called the anode, will attract negatively charged non-metal ions. The non-metal ions lose electrons to the anode and are discharged as non-metal atoms.
Is corrosion reverse of metal extraction?
Type your answer here... most of the metals naturally exist in combined formed during metallurgy the metals are extracted from their ores by reduction process in pure metallic state, metals are unstable and considered to be in the excited state.therefore,the extracted metals have a tendency to go to thermodynamically stable state , which is otherwise known as corrosion.

Why is carbon used to extract metal from ores?
Carbon is used to extract metal from ores through a process called reduction because carbon is a strong reducing agent. When carbon reacts with metal oxides in the ore, it removes oxygen from the metal oxide, leaving behind the pure metal. This process is known as smelting and is commonly used for extracting metals such as iron from their ores. Carbon's high reactivity and abundance make it a cost-effective and efficient choice for metal extraction.

What metal oxides can be converted to the metal by carbon reduction but not by hydrogen reduction?
any metals below carbon in the reactivity series. :)
Why is extraction of copper termed as auto reduction?
Extraction of copper is termed as auto reduction because the process involves the reduction of copper oxide minerals to form copper metal by using carbon monoxide produced through the oxidation of carbon. This essentially means that the copper oxide is reduced to copper in the presence of its own oxides without the need for an external reducing agent.
