The activity series which metals lose their electrons more easily answer key

In the activity series, the metal that loses their electrons more easily are less reactive compared to metals that forms positive ions. In addition, an activity series is a list of substances in order from most reactive to least reactive and its relative reactivity can be determined by using a number of chemical reaction. Moreover, metals in the activity series need to lose their electrons, or be oxidized or some metals will tend to stay in their neutral state.

radioactive decay occurs in unstable atomic nuclei – that is, ones that don't have enough binding energy to hold

the nucleus together due to an excess of either protons or neutrons.
