Sodium (Na) atoms are larger than chlorine (Cl) atoms, but in NaCl sodium ions (Na+) are much smaller than chloride (Cl-) ions. Discuss why there is a change in size of each element (i.e., why is Na --> Na+ a decrease in size and Cl --> Cl- is an increase in size).

Consider the following information for sodium and chlorine: Atomic radius: Na (186 pm) and Cl (100pm) Ionic radius: Na+(102pm) and Cl-(181pm) Why does the atomic radius decrease while ionic radius increase? The outermost electrons in chloride experience a larger effective nuclear charge than those in the sodium cation do. Monatomic ions are bigger than the atoms from which they are formed. The outermost electrons in chloride experience a smaller effective nuclear charge than those in the sodium cation do. The...
When sodium chloride dissolves in water, the ions dissociate: NaCl (s) Na+ (aq) + Cl- (aq) What is the sign of the change in Gibbs free energy (DG) for each process in the forward direction?
When sodium chloride dissolves in water, the ions dissociate: NaCl (s) --> Na+ (aq) + Cl- (aq) Consider the equation, DG = DH - TDS. For each dissolving process, substitute the signs of DG and DH into the equation and predict the possible sign(s) for the entropy (DS). Explain why you chose this sign(s). Does the sign for entropy change seem to make sense? Explain.
3.13 g of sodium (Na) react with 7.17 g of chlorine (Cl) to produce 10.3 g of sodium chloride (NaCl). What is the mass percent of chlorine in sodium chloride? 43.7% is chlorine. O 30.3% is chlorine. 50.0% is chlorine. 69.6% is chlorine.
When sodium chloride dissolves in water, the ions dissociate: NaCl (s) à Na+ (aq) + Cl- (aq) Write ionic equations, similar to the one above, that describe how NaNO3 and NaCH3COO each dissociate as they dissolve in water. Include heat as a reactant or product in each equation

Q 6: Four ions (Na+Na+, Cl−Cl−, Na+Na+, and Cl−Cl−) in a row are each separated from their nearest neighbor by 4.5×10−10 mm . The charge of a sodium ion is +e+e and that of a chlorine ion is −e−e. Determine the electric force exerted on the chlorine ion at the right end of the row due to the other three ions. (+x+x to the right) Express your answer with the appropriate units.
four ions (na, cl, na, and cl) in a row each separated from their nearest neighbor by 2.0x10^-10m. The charge of a sodium ion is +e and that of a chlorine ion is -e. determine the electric force exerted on the chlorine ion at the right end of the row due to the other three ions.
Q2. Sodium and chlorine react to form sodium chloride: 2 NaCl(s) 2 Na(s) + Cl2(8) What is the theoretical yield of sodium chloride for the reaction of 55.0 g Na with 67.2 g Cl2?
If S^2- larger or smaller than Cl- a. these two ions have the same size b/c they have the same number of electron b. s^2- is larger b/c it has fewer protons than cl- c. s^2- is larger b/c it exhibits greater electron repulsion d. cl- is larger b/c it has higher mass than s2-
