The electrons
The valence electrons are the part that takes place in a chemical reaction.

the valence electrons
Proton and Neutron do not take part in chemical reaction. Only electron takes part in the reaction.
Electrons - the valence electrons
Electrons are the parts of an atom that participate in chemical reactions. Specifically, it is the outermost electrons, known as valence electrons, that are involved in forming chemical bonds with other atoms.

An atom. However it should be noted that generally the valence electrons in an atom take part in a chemical reaction.
The smallest part of an element that can take part in a chemical reaction is an atom. Atoms are composed of protons, neutrons, and electrons, and they are the building blocks of all matter in the universe.
the number of protons and neutrons
No. An atom is made of Elements. Name of element is decided by number of Protons, containing in it's Nucleus. Two or more different types of elements react with each other to form compound in what is called as chemical reaction.
