Abstract
Properties of the noble gases, alkali metals, alkaline earth metals and halogens.
Concept preview
What you will be able to do
- 01Explain why elements in a group form a family
- 02State the characteristic properties of the noble gases, alkali metals, alkaline earth metals and halogens
- 03Describe how reactivity changes within these families
A chemical family (or group) is a column of the periodic table whose elements share similar chemical properties. The reason is electron configuration: members of a group have the same number of valence electrons, and since valence electrons control chemistry, the whole family reacts in similar ways. Four families are especially important in Chemistry 11.
