Reactivity of elements:
- An element's reactivity is its tendency to lose or gain electrons.
- The reactivities of elements can be predicted by periodic trends (patterns within the Periodic Table.)
- The trend for metals is that they become more reactive going down and less reactive going across in the periodic table.
