Chlorine is an atom. Sodium is a metal, a solid. When Na (sodium) and Cl (Chlorine) react, electrons are exchanged, and the properties of the compound NaCl are different from both sodium and Chlorine. And Chlorine gas is just a state of matter, if in a low enough temperature, it will freeze, becoming a solid. Like
for the conductance of electricity freely moving ions and electrons are necessary. But in NaCl (in solid form) Na positive ion and Cl negative ion are held together by strong electrostatic force and there is no freely moving ion in NaCl (in solid state) therefore NaCl does not conduct electricity in solid form.
The balanced equation would beNa + Cl -> NaCl Basically this reaction can be done by plunging a piece of sodium into a glass gas filled with chlorine gas. A lot of heat is produced in this reaction.
The common ion is chloride (Cl-).
The water solution of sodium chloride is neutral; the solid NaCl is neutral. After dissociation are formed the cation Na+ and the anion Cl-.
NaCl---------------→Na+ + Cl-
The equation is: NaCl----------Na++ Cl-
To determine how many grams of chlorine gas (Cl₂) are produced from the decomposition of sodium chloride (NaCl), we start with the balanced chemical equation for the reaction: 2 NaCl → 2 Na + Cl₂. From the molar mass of NaCl (approximately 58.44 g/mol), 7.5 grams of NaCl corresponds to about 0.128 moles. According to the stoichiometry of the reaction, 2 moles of NaCl produce 1 mole of Cl₂, so 0.128 moles of NaCl would yield 0.064 moles of Cl₂. The molar mass of Cl₂ is approximately 70.90 g/mol, resulting in about 4.54 grams of Cl₂ being produced.
Na+ + Cl- --> NaCl NaCl = salt.
Sodium chloride is dissociated in water: NaCl---------------------Na+ + Cl-
Throw some on the kitchen bench. If it stays there, it's not a gas. If it doesn't spread out into a thin film, it's not a liquid. So.... Actually, standard table salt, or NaCl(Sodium Chloride), at room temperature is a solid. It can be melted which means it can become a liquid and release vapors which are gas. When NaCl melts the Na ions and Cl ions can separate.
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.
Salt (NaCl) is white, solid, salty, soluble in water, usually found in small granules, etc. Sodium (Na) is a silver/white, highly reactive alkali metal. Chlorine (Cl) is a greenish gas, and a halogen.
