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.

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 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.
What is the chemical symbol for lapis lazuli?
(Na,Ca)8[(S,Cl,SO4,OH)2|(Al6Si6O24)].
Give the letters of two elements in the same period?
Na, Mg -- also Al, Si, P, S, Cl, Ar
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 is: Cl,S, Si, Al, Na.
S na cl mg witch one is largest?
Na :)
If you mix aqueous of table salt and silver nitrate what do you get?
Only the Ag+ and the Cl- ions will react to precipitated AgCl;Na+ and NO3- are tribuned (= stay unchanged in solution).Ag+ + Cl- --> (AgCl)s
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--------
Arrange the following elements from greatest to least tendency to accept an electron. Cl S Si Mg Na?
From greatest to least tendency to accept an electron, they are F, O, C, Li, and Be.
What is the dissociation of Na3PO4?
NaCl (sodium chloride), when placed into water, will dissociate respectively into sodium cations (Na+) and chloride cations (Cl-) when placed into water. Cl- becomes attracted to the hydrogen molecules in water whereas Na+ becomes attracted to the oxygen in the water thus forming salt water.
