Sodium chloride (NaCl) does not act as a buffer because it does not contain any species that can either donate or accept protons to resist changes in pH. Buffers are typically solutions containing a weak acid and its conjugate base, or a weak base and its conjugate acid, which can help stabilize and maintain the pH of a solution. NaCl simply dissociates into ions without any proton transfer involved.
Ionic compounds tend to shatter when struck with a hammer. This is due to the crystal structure formed by an ionic compound, which is basically repeating units of negatively and positively charged ions in some sort of geometric arrangement. When struck, ions of similar charge and pushed next to each other. These ions repel and the whole crystal will then cleave apart along the crystal pattern. example: Left undisturbed NaCl crystal, right struck Na Cl :crys.tal breaks along crystal pattern Na Cl Na Cl Na Cl Cl Na Cl Na Cl Na Na Cl Na Cl Na Cl Na Cl Cl Na Cl Na Cl Na Cl Na Na Cl Na Cl Cl Na Metallic bonds are better pictured as an electron sea, where all the metal atoms that are participating are freely sharing electrons amongst each other. Because of this there are no localized charges to repel each other, making metallic bonds far less susceptible to shattering.
NaCl-----------------Na+ + Cl-is a dissociation reaction.
You would need to add 35.5 g of Cl to combine with 23 g of Na. This is because Na and Cl combine in a 1:1 ratio by mass based on their atomic weights (Na = 23 g/mol, Cl = 35.5 g/mol).
Na+ is the sodium cation, Cl- is chlorine anion.
The net ionic equation for Na^+ + Cl^- is Na^+ + Cl^- → NaCl, which represents the formation of sodium chloride when Na^+ and Cl^- ions combine. This equation shows the reactants and products without including spectator ions that do not participate in the reaction.
2: Na+, Cl-
NaCl---------------→Na+ + Cl-
Na+ + Cl- --> NaCl NaCl = salt.
na + cl- na - electronic configuration 2,8,1 cl - electronic configuration 2,8,7 na -e --> na + cl +e -->cl - so they formed a ironic bond between them
Na+ and Cl- are spectator ions.
Na is sodium (11) Cl is Chlorine (17)

The equation is: NaCl----------Na++ Cl-

The symbol for sodium is Na. The symbol for chlorine is Cl.
Hydrochloric acid and sodium hydroxide yield salt and water H+ + Cl- + Na+ + OH- --> Na+ + Cl- + H2OComment:In solutions you better leave unchanged ions ( Cl- and Na+) out of the balanced equation: called to be 'tribune ions' (people on the tribune don't take part in the 'match'):H+ + OH- --> H2O This looks simpler than: H+ + Cl - + Na + + OH- --> Na + + Cl - + H2O
NaCl --> Na+ + Cl- You could write water on either side I suppose, but it is negligible. I've also seen H2O written over the arrow.
