WebAug 15, 2024 · A common characteristic of most Alkali Metals is their ability to displace H 2 (g) from water. This is represented by their large, negative electrode potentials. In this event, the Group 1 metal is oxidized to its metal ion and water is reduced to form hydrogen gas and hydroxide ions. WebYes, because if wood floats then other things made out of wood should also float. Wood has the characteristic property of floating.
