Lesson Title:
Today we are learning about
What are the properties of Group 7 elements?
Remember to check for PROGRESSFocus on Knowledge, Skills and Understanding
Success Criteria:
You will show your learning by...
The elements in Group 7 of the periodic table are known as the halogens and have similar reactions because they all have seven electrons in their outer shell.
The halogens are non-metals and consist of molecules made of pairs of atoms.
Students should be able to describe the nature of the compounds formed when chlorine, bromine and iodine react with metals and non-metals.
In Group 7, the further down the group an element is the higher its relative molecular mass, melting point and boiling point.
In Group 7, the reactivity of the elements decreases going down the group.
A more reactive halogen can displace a less reactive halogen from an aqueous solution of its salt.
Students should be able to explain how properties of the elements in Group 7 depend on the outer shell of electrons of the atoms
Students should be able to predict properties from given trends down the group.
Many transition elements have ions with different charges, form coloured compounds and are useful as catalysts.
Students should be able to exemplify these general properties by reference to compounds of Cr, Mn, Fe, Co, Ni, Cu.

AFL/Key Questions:
What is the common name given to the group 7 elements?
The halogens
Describe the trend in boiling point and melting point of elements as you go down group 7?
As you go down group 7, the melting and boiling points of the elements increases.
Describe the trend in reactivity of elements as you go down group 7?
As you go down group 7, the reactivity of the elements decreases.
Write a word equation for the reaction between sodium chloride and fluorine. What type of reaction is this?
Sodium chloride Fluorine -> Sodium Fluoride Chlorine. This is a displacement reaction as the more reactive halogen displaces the less reactive halogen from its compound.
In terms of electron structure, whAt do all group 7 elements share in common?
They all have 7 electrons in their outermost shell
List the elements of group 7 in order of reactivity.
Fluorine, Chlorine, Bromine, Iodine, Astatine
Many transition elements are also useful as catalysts. What is a catalyst?
A catalyst is a substance which speeds up a chemical reaction without being used up itself.
List the general properties of compounds of transition elements
