The electrons farthest from the nucleus of the atom
No, it results from the interaction of electrons.
No, absolutely not. There are much smaller particles, first Electrons (which are part of reactions), Then Quarks that neutrons and protons are made of (and are part of reactions), and much, much smaller particles after that also are involved in chemical reactions.
The valence electrons.
The valence electrons (electrons present in the outer most shell) are involved in a chemical reaction.
The subatomic particles that govern potential chemical reactions among elements are known as electrons.
Chemical reactions depends on the valence electrons.
Chemical reactions involve valence electrons and not protons.
These are the electrons which partake in chemical reactions.
The electrons
Valence electrons are important for the chemical reactions.
In chemical reactions, it is the valence electrons that are generally involved.
