Group 7 Flashcards
What are the elements in Group 7 of the periodic table known as?
Halogens.
What is a common feature of halogens?
They all have seven electrons in their outer shell.
What is the nature of compounds formed when halogens react with metals and non-metals?
Students should be able to describe this.
How do relative molecular mass, melting point, and boiling point change down Group 7?
They increase as you go down the group.
How does reactivity change in Group 7 going down the group?
Reactivity decreases.
What can a more reactive halogen do to a less reactive halogen in a displacement reaction?
Displace it from an aqueous solution of its salt.
What should students be able to explain regarding Group 7 elements?
How their properties depend on the outer shell of electrons and predict properties from given trends down the group.
