Which statement describes the general trends in atomic radius and first ionization energy as the elements in Period 3 are considered in order from Na to Cl? (1) Atomic radius increases, and first ionization energy decreases.

(2) Atomic radius decreases, and first ionization energy increases.

(3) Atomic radius and first ionization energy both increase.

(4) Atomic radius and first ionization energy both decrease.

adding or remove a gaseous reactant or product changes the concentrations. if the concentration of reactant or product is increased, the system will shift away from the side in which concentration was increased (i.e. if the concentration of reactants is increased, the system will shift toward the products. if more products are added, the system will shift to form more reactants). conversely, if the concentration of reactant or product is decreased, the system will shift toward the side in which concentration was decreased (i.e. if reactants are removed, the system will shift to form more reactants. if the concentration of products is decreased, the equilibrium will shift toward the products).
