A standard chemical reaction always and only involves a change in the electron configuration of the atom (either the number of electrons or their energy configuration).
If the nucleus is affected (either the number of protons or electrons), then it is designated as a nuclear reaction, and this is quite different.
The valence shell electrons participate in reactions.
The part of atom that engages in chemical reaction is the element when it reach with another element from a chemical reaction and they form a chemical compound.
from charles jimingo
generally the valence electrons are involved in chemical reactions
The electrons are directly involved with chemical changes.
The outer energy level electrons.
the electrons
probably electrons
Electrons
It is the part of the atom with the greatest mass
Positive. The only (typical) parts of atoms that move are electrons which have a negative charge; therefore, if a neutral atom loses an amount of electrons (negative charges), the atom has more positive charges (from the protons) than negative charges which makes the atom positively charged overall.

There is a solid region in the atom, he named this part of atom as Nucleus.
Nucleus
the outer energy level electrons.
The outer shell electrons of an atom are involved in chemical bonding
the answer is the outermost electron shell
The electrons
The valence electrons of the atom.

outer energy level electrons... called valence electrons
The outer or valence electrons are the ones involved in bonding.Valence electrons
