Physical and atomic properties of the elements . . .
Discusses the trends in first ionisation energy, atomic radius, electronegativity, conductivity, melting point and boiling point as you go across the period from sodium to argon.
Reactions of the Period 3 elements . . .
The reactions of the elements from sodium to argon with water, oxygen and chlorine.
Physical properties of the oxides . . .
Discusses the link between the physical properties of the oxides of the elements from sodium to chlorine and their structure and bonding.
Acid-base behaviour of the oxides . . .
Reactions of the oxides with water, and their acid-base behaviour.
Chlorides of the Period 3 elements. . .
The physical properties of the chlorides of the elements from sodium to sulphur, their structure and bonding, and their reactions with water.
Hydroxides of the Period 3 elements . . .
The acid-base behaviour of the "hydroxides" (using the term in the widest possible sense) of the Period 3 elements.
