Carbon 14 is a naturally occurring stable

Explain the difference in reactivity of the elements based on their electron configurations.

How can you improve the percent yield of copper in this lab? check all possible strategies that will you do so. measure reactants precisely. stir to the reaction take place. chill the reactants before combining them. wait patiently until the reaction completes. make sure to recover as much copper as possible.
