The phrase that describes valence electrons is "the electrons in an atom's outermost energy level."

Valence electrons are the electrons that reside in the outermost shell or energy level of an atom. These are the electrons that are involved in chemical bonding and determining the chemical properties of an element.
To determine the number of valence electrons in an atom, you can refer to the periodic table. The group number or column number of the element in the periodic table indicates the number of valence electrons. For example, elements in Group 1 (such as hydrogen and lithium) have 1 valence electron, while elements in Group 18 (such as helium and neon) have 8 valence electrons (except for helium, which has only 2 valence electrons as it belongs to the first period).
