Understanding Chemistry

 

PERIODIC TABLE GROUP 4 MENU

 


Note:  If you use the current IUPAC (international Union of Pure and Applied Chemistry) system for group numbering, you will probably know what I call Group 4 as Group 14. My reasons for not using the IUPAC system are discussed on this page in the Questions and Comments section.


The trend from non-metal to metal . . .

Discusses the trend from non-metallic to metallic behaviour as you go down Group 4. Describes the structures and physical properties of the elements, and some important atomic properties.

Oxidation state trends . . .

Looks at the increasing tendency towards an oxidation state of +2 as you go down the Group.

Group 4 chlorides . . .

Describes and explains the differences between the chlorides of carbon, silicon and lead as required by UK A level chemistry syllabuses.

Group 4 oxides . . .

Describes and explains the differences between the dioxides of carbon and silicon, and looks at the trend in acid-base behaviour of the oxides as you go down the Group.

Some chemistry of aqueous lead(II) ions . . .

Describes the reactions of lead(II) ions in solution with hydroxide ions, chloride ions, iodide ions and sulphate ions.
