The boiling points of the noble gases increase with increasing relative atomic mass (going down the group). 5.1.2.5 The elements in Group 1 of the periodic table are known as the alkali metals and have characteristic properties because of the single electron in their outer shell.: In Group 1, the reactivity of the elements increases going down the group. Describe the reactions of the first three alkali metals with oxygen, chlorine and water. Explain how properties of the elements in Group 1 depend on the outer shell of electrons of the atoms. Predict properties from trends down the group. 1 Define the Group 1 metals. Describe the properties and describe how the reactivity changes as you move down the group. Draw the electronic shells of the Group 1 metals and link to the reactivity. Describe how properties of the elements in Group 1 depend on the outer shell of electrons of the atoms. Predict the properties of caesium and rubidium based on their electronic structure. Demonstrate the reactivity of the Group 1 metal in water. Demonstrate that alkali metals form alkaline solutions in water using UI. Students can investigate the colours of compounds of alkali metals using flame tests.

The halogens are non-metals and Describe the nature of the compounds formed when chlorine, bromine and iodine react with metals and non-metals. 1 Define the elements of Group 7. Describe the properties of the elements in Group 7 including the electron shell configuration. Demonstrate the relative reactivities of the halogens by reacting potassium halogens solution (eg iodide) with bromine or chlorine. Video clip: YouTube:
