Sodium (Na) and chlorine (Cl) make sodium chloride (NaCl), or salt.
The metal cation Na transfers one of its electrons to nonmetal anion Cl to achieve noble gas electron configuration for both ions. Sodium, which usually has one valence electron when neutrally charged, would lose it to have full lower level valence electron shell, while chlorine, which usually has 7 valence electrons when neutrally charged, would gain sodium's electron to have complete its current valence electron shell.
Since the Na atom would then have a positive charge for having 11 protons but 10 electrons while the Cl atom would be negatively charged because of its 17 protons but 18 electrons, their opposite charges attract each other together, forming a lattice structure of sodium and chlorine atoms strongly bonded together in sort of an ABABAB pattern.

What is a chemical equation for the dissociation of a soluble salt in water?
An example is the dissociation of NaCl in water: NaCl (s) -> Na+ (aq) + Cl- (aq). Here, NaCl breaks apart into its constituent ions, Na+ and Cl-, when dissolved in water due to the attraction between the ions and water molecules.
Is dissolving salt in water a chemical or physical change?
Physical (not chemical) changesNaCl(s) → Na+(aq) + Cl-(aq)Added:These are NOT chemical changes. In solid NaCl there are already Na+ and Cl- ions present in the (fully ionic)crystallic matrix. These ions are only separated by the water molecules. This is exactly what is called: 'dissolving'
What is the ionic equation for barium chloride plus sodium sulphate?
The chemical equation is:Ba+ + 2 Cl- + 2 Na+ + SO4- = BaSO4(s) + 2 Cl- + 2 Na+
What is the chemical symbol for lapis lazuli?
(Na,Ca)8[(S,Cl,SO4,OH)2|(Al6Si6O24)].
What cause salt to disappear in heat water?
It doesn't disappear so much as dissolve. The ionic bonds that form the crystal lattice between sodium (Na) and chlorine (Cl) are broken in water, causing the ions to float about in the water.

How do you prepare thiokol rubber?
we will prepare thiokol rubber from 1,2 dichloroethane and sodiumpolysulphide.The reaction is:cl-CH2-CH2-cl + Na-S-S-Na + cl-CH2-CH2-cl--------------> -----(----CH2-CH2-S-S-CH2-CH2----)n--------
Which of the two following two elements will likely form an ionic bond na and k na and cl mg and li s and cl?
Na and K are both metals and do not react Na and Cl are metal and non metal respectively and will form ionic compound, NaCl or table salt or sodium chloride Mg and Li are both metals and do not react S and Cl are both non metals and will give covalent compounds
What is S Si Na Al and Cl in order from highest ionization energy to lowest?
The order from highest to lowest ionization energy is Cl > Al > Si > Na > S. This is because ionization energy generally increases from left to right and from bottom to top in the periodic table.
What is the equation of sodium cholride dissolving in water?
Sodium chloride disassociates in water to produce Na+ and Cl - ions.NaCl + H2O = Na+ aq and Cl- aq.

What is a balanced ionic equation for sodium chloride in water?
The balanced ionic equation for sodium chloride (NaCl) in water (H2O) is: NaCl (s) → Na+ (aq) + Cl- (aq) This equation shows the dissociation of sodium chloride into its ions sodium (Na+) and chloride (Cl-) in water.
