If element X have 5 valence electrons it will more than likely gain 3 electrons to fill its octet to become stable. Gaining the 3 electrons is much easier for the atom than if it were to give away it's 5 valence electrons. Elements with 5 valence electrons that could represent element X are:
Election current because voltage is a measurement, information doesn't apply to all electrical devices and the wires within are usually copper bc it conducts and hardly ever will the wires be anything different because copper is cheap
