The outer shell electron(s) of any element that engage in chemical interactions; such as ionic or covalent bonding.
Valence electrons are the electrons involved in chemical reactions.
what term describes elements that contain the same number of valence electrons
group
Valence electrons are the outermost electrons in an atom that are involved in forming chemical bonds with other atoms. They determine the atom's reactivity and ability to form compounds. The number of valence electrons can also be used to predict an element's chemical properties.
Halogens
The VALENCE Shell. In any chemical reaction it is the electrons in the Valence Shell that do the reacting. Any inner shells of electrons do NOT take part in a chemical reaction.
alkali earth metals
Electrons in the outermost shell are valence electrons!
Valence electrons
the electrons in the outermost shell of an atom are considered to be the valence electrons.
