exothermic chemical reactions
The general chemical formula for oxidation is A + B -> AB. This represents a chemical reaction where substance A loses electrons and substance B gains electrons.
This is an ionic bond.
their gain or loss of electrons
No, they arent. Valence electrons are the amount of electrons the element has in its outermost shell. Electrons dont bond, they can either be shared or transferred. An ionic bond transfers electrons and a covalent bond shares electrons.
The chemical change in which a substance becomes more negative could be the ionization of the substance. Means that the substance becomes more negatively charged and that is due to it being ionized. It tends to gain more electrons in order to fill its valence shell to become a stable substance.
A covalent bond is formed when electrons are transferred from atom to atom.
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.

exothermic chemical reactions
By abstracting electrons from or donating electrons to some other chemical substance.
In the reaction as written below, the number of moles of electrons transferred is equal to the coefficient of the electrons in the balanced chemical equation. If you provide the specific reaction, I can help you determine the number of moles of electrons transferred.
Electrons are the subatomic particles specifically responsible for combining atoms to form a new substance. They are involved in forming chemical bonds between atoms by being shared or transferred between them.
Depends on the chemical substance
Ionic bonds are formed by transferring electrons, while covalent (molecular) are formed by sharing electrons.
Protons, electrons, and photons can be transferred or shared when two atoms react chemically. Neutrons are typically not involved in chemical reactions as they are located in the nucleus and are not directly involved in forming chemical bonds.
