Halogen are the most reactive due to their electronic configuration
Having resources? i guess...
maybe it is critical thinking?
I think it's reactivity. but i'm not sure.
The rate of dissolution of a solid solute into the solution decreases when you stop stirring it. Generally, stirring increases the dissolution rate of a solid into a solution. An example is coffee with sugar, the sugar dissolves faster when stirred versus when left to dissolve on its own.
