Sodium is chemically unstablebecause sodium has onevalence electron and needseight valence electrons to bechemically stable.

Chlorine is chemically unstablebecause Chlorine has sevenvalence electrons and needseight valence electrons to bechemically stable.

Na

Sodium donates one valenceelectron to chlorine. Sodium’svalence shell has eightelectrons, making sodiumchemically stable.

Cl

Chlorine receives the electronfrom sodium. Chlorine’svalence shell has eightelectrons, making chlorinechemically stable.

Donates

Fig. 2-5.

Sodium donates one valence electron to chlorine in a chemical reaction that forms the compound known as salt.
