Answer question numbers 3.1-3.4 on the basis of your understanding of the
following paragraph and the related studied concepts. The arrangement of metals
in a vertical column in the decreasing order of their reactivities is called the
reactivity series or activity series of metals. The most reactive metal is at the top
position of the reactivity series. The least reactive metal is at the bottom of the
reactivity series. Hydrogen, though a non-metal, has been included in the activity
series of metals only for comparison. Apart from it, the hydrogen atom also has
tendency to lose its valence electron and form cation like the behavior shown by
metals. Thus, HH+e
