the valence electrons
orbital
The valence electrons are the part that takes place in a chemical reaction.
The electrons
The electrons that participate in chemical bonds are located in the "valence shell" or outer energy level of that atom. They are known as the valence electrons, and they are the only part of the atom that participates in a chemical reaction.
Electrons.
Only the valence electrons
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.
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.
Electrons - the valence electrons
The electrons (especially the valence electrons)
An atom. However it should be noted that generally the valence electrons in an atom take part in a chemical reaction.
Valence electrons occur in the outermost energy level, or valence shell, of an atom. These electrons are involved in the formation of chemical bonds and determining the atom's reactivity and chemical properties.
