The phrase that describes a valence electron is "an electron in the outer energy level of an atom."
The phrase that describes a valence electron is "an electron in the outer energy level of an atom." Valence electrons are the electrons in the outermost energy level or shell of an atom. They are involved in chemical reactions and determine the atom's ability to bond with other atoms. To understand this concept, you can use the periodic table. The periodic table provides information about the number of valence electrons for each element. The group number of an element corresponds to the number of valence electrons it has. For example, elements in group 1 have 1 valence electron, elements in group 2 have 2 valence electrons, and so on.
