Answer:
Sodium is a silver-colored metal which is soft enough to cut with a knife. It is an extremely reactive metal, and is always found naturally in ionic compounds, not in its pure metallic form. Pure sodium metal reacts violently (and sometimes explosively) with water, producing sodium hydroxide, hydrogen gas, and heat:
2Na(s) + 2H2O(l) ——> 2NaOH(aq) + H2(g)
Chlorine is a poisonous, yellow-green gas, with a very sharp odor, and was used in gas warfare during World War I.
Sodium and chlorine react with each other, however, to produce a substance that is familiar to almost everyone in the world: sodium chloride, or table salt:
2Na(s) + Cl2(g) ——> 2NaCl(s)
It is easy to see why this reaction takes place so readily when we look at it on an atomic level: sodium has one electron in its outermost (valence) shell, while chlorine has seven electrons in its valence shell. When a sodium atom transfers an electron to a chlorine atom, forming a sodium cation (Na+) and a chloride anion (Cl-), both ions have complete valence shells, and are energetically more stable.
The reaction is extremely exothermic, producing a bright yellow light and a great deal of heat energy.
