Reactivity across periodic table
WebThe reactivity series of metals, also known as the activity series, refers to the arrangement of metals in the descending order of their reactivities. The data provided by the reactivity series can be used to predict whether a … WebNov 2, 2024 · Correct answer: Atomic radius decreases as you move left to right on the periodic table. As atomic number increases, so does the number of positive protons in the nucleus. To the far left of a period, electrons are widespread within a new electronic shell.
