Question 2 of 14
2. Question
Use some of the following words to fill in the blanks.
Lower, higher, increase, decrease, chlorine, iodine
-
Complete the statement:
As you go down group 7, density, melting points and boiling points .
That means that fluorine will have a boiling point than chlorine.
So, bromine is denser than and chlorine has a boiling point than iodine.

Use some of the following words to complete the statement and word equation below.
More, less, mixture, aqueous, bromine, chlorine, chloride, bromide, compound, element
-
Complete the statement and equation:
Halides get reactive as you go down the group. This can be seen in displacement reactions where one element displaces another in an ionic .
For example –
Chlorine + sodium bromide → + sodium
