If an atom has 7 valence electrons, how many electrons does it need to gain to achieve a stable electron configuration?

Six solutions are made, each with a y concentration of 1.0 μm and varying concentrations of ab as shown below. based on the concentrations, rank the solutions in decreasing order of reaction rate.
