redox reaction
When a substance gains an electron or electrons, this is known as "reduction". For every reduction reaction, there is also an oxidation reaction. So, whatever substance "gave" the electrons, underwent oxidation.

When a molecule gains an electron, it has been reduced.
This substance is called an Oxidant or an Oxidising Agent .It oxidises the other substance and reduces itself .
When chlorine becomes chloride, the chlorine gains an electron to form an anion. This process is called oxidation. Oxidation always occurs with reduction (loss of an electron from another substance) in an oxidation reduction reaction.
This is called a redox reaction. An atom that loses an electron is oxidized and an atom that gains an electron is reduced.
In the reaction, bromine gains an electron and forms a bromide ion (Br-). This results in a decrease in the oxidation state of the bromine atom from 0 to -1.
When sodium reacts with bromine, they form sodium bromide. This is a redox reaction where sodium loses an electron to bromine, which gains an electron to form the bromide ion. The reaction is highly exothermic and can be violent if not controlled.
An atom that has gained an electron has a negative charge and is called an anion.
In the reaction, bromine gains an electron to become a bromide ion with a negative charge. This process is known as reduction because the bromine atom is gaining an electron, which results in a decrease in its oxidation state.
negative, minus 1 for each electron gained. e.g Cl gains 1 electron so is Cl- where as O gains two electrons so is O2-
A redox reaction involves the transfer of electrons between reactants, leading to changes in oxidation states. The substance that loses electrons is oxidized, while the substance that gains electrons is reduced. This process is essential in various chemical reactions and electron transfer in biological systems.
