Sodium and chlorine react to form the ionic compound sodium chloride.
The chemical equation for this reaction is:
2Na+Cl2→2NaCl 2\text{Na} + \text{Cl}_2 \rightarrow 2\text{NaCl} 2Na+Cl2→2NaClWrite a word equation for this reaction.
Describe the changes in electronic configurations when sodium reacts with chlorine to form the ionic compound sodium chloride (NaCl\text{NaCl}NaCl). Include the electronic configurations of the atoms and the resulting ions, and show the charges on the ions. (Atomic numbers: Na=11\text{Na} = 11Na=11, Cl=17\text{Cl} = 17Cl=17)
Calculate the mass of sodium chloride (NaCl\text{NaCl}NaCl) that forms when 0.46 g of sodium reacts completely with chlorine. (Relative atomic masses, ArA_rAr: Na=23\text{Na} = 23Na=23, Cl=35.5\text{Cl} = 35.5Cl=35.5)
