The anode electrode loses loses electron and oxidation half reaction occurs at it.
An element is REDUCED. By that, it means that an element of a compound or an element in itself has gained electron/s when the reaction occurs. You can find this out when you see a change in their oxidation number.
ionization energy
An example of an oxidation reaction is the reaction between magnesium and oxygen to form magnesium oxide: 2Mg + O2 -> 2MgO. In this reaction, magnesium loses electrons to form magnesium ions, Mg²⁺, thereby undergoing oxidation.
A redox reaction is a chemical reaction in which one substance loses electrons (oxidation) while another gains electrons (reduction). This transfer of electrons leads to a change in the oxidation states of the substances involved.
A redox reaction is a type of chemical reaction that involves the transfer of electrons between two species. One compound loses electrons (oxidation) while another gains electrons (reduction). This transfer of electrons results in changes in the oxidation states of the elements involved.
the nickel metal
In a galvanic cell made with silver and nickel electrodes, the nickel electrode undergoes oxidation as it loses electrons, which travel through the external circuit to the silver electrode where reduction occurs. This flow of electrons generates an electric current in the cell.
An element is REDUCED. By that, it means that an element of a compound or an element in itself has gained electron/s when the reaction occurs. You can find this out when you see a change in their oxidation number.
If one substance is losing electrons (where it is gaining charge, or oxidizing), we must assume those electrons are going to another substance in the reaction, which will cause the charge to go down, or reduce. This type of equation is called a Redox (reduction-oxidation) reaction.
A redox reaction can be determined by looking at whether there is a transfer of electrons between the reactants. If one substance loses electrons (oxidation) and another gains electrons (reduction), then it is a redox reaction.
ionization energy
In this reaction, Lithium is oxidized to Lithium ions (Li+) and Bromine is reduced to Bromide ions (Br-). Oxidation occurs when an element loses electrons (in this case, Lithium loses an electron), while reduction occurs when an element gains electrons (Bromine gains an electron).
An example of an oxidation reaction is the reaction between magnesium and oxygen to form magnesium oxide: 2Mg + O2 -> 2MgO. In this reaction, magnesium loses electrons to form magnesium ions, Mg²⁺, thereby undergoing oxidation.
One can determine if a chemical reaction is a redox reaction by identifying if there is a transfer of electrons between the reactants. In a redox reaction, one substance loses electrons (oxidation) while another gains electrons (reduction). This transfer of electrons indicates a redox reaction is taking place.
A reducing agent loses electrons and is thereby oxidised.
You wouldn't expect strontium to gain electrons in a chemical change.
In a dry-cell battery, the redox reaction that takes place involves the oxidation of zinc (Zn) at the anode and the reduction of manganese dioxide (MnO2) at the cathode. The overall chemical reaction can be represented as: Zn(s) + MnO2(s) + H2O(l) -> ZnO(s) + Mn(OH)2(s).
