It depends on the type of chemical reaction. A reduction-oxidation reaction (redox reaction) involves the transfer of electrons, thus electrons are involved, for example
2Mg(s) + O2(g) > 2MgO(s)
However, reactions involving acids or bases involve the movement of protons (acids are proton donors, bases are proton acceptors) for example:
HCl(aq) + H2O(l) > Cl-(aq) + H3O+(aq)
Furthermore, there are nuclear reactions which can involve almost any particle. Therefore, the type of reaction determines the particle or type of particle involved.
no chemical reaction takes place . when electrons are shared it is known as covalent bond
If you mean where it takes place inside an atom, then the answer is this: in the nucleus.
The valence electrons are the part that takes place in a chemical reaction.
These initial substances are the reactants.
reactant
When a chemical reaction takes place, the compound formed is called the product. The product is the end result of the chemical reaction, typically formed from the reactants that underwent a rearrangement of atoms.
The atoms of the reactants are rearranged to form new products that are different in chemical composition and properties from those of the reactants.

chemical reaction takes place in rancidity
A chemical equation is defined as the short-hand representation of a true chemical reaction with the help of symbols and formula.We must finish our chemical reaction with as many atoms of each element as when we started.The chemical reaction takes place on the reactant side forming the products.
These initial substances are the reactants.
