Quizplus · Accepted Answer

The activity series lists elements in order of their likelihood to undergo redox reactions. The higher an element is on the activity series, the more likely it is to undergo such reactions. Elements that are lower on the series, like silver (Ag), are less likely to undergo redox reactions and therefore less likely to release hydrogen gas upon reaction with water or acid. Ni, Al, and Mg are all higher on the activity series and more likely to release hydrogen gas upon reaction.
