Year 9 Halogens and review. (14/10/2024)

At room temperature Cl₂

At room temperature, the physical state of bromine is:

At room temperature Br₂

At room temperature I₂

Chlorine gas is

Bromine is

Iodine is

Astatine is likely to be

As group VII is descended the melting point of the halogens

What is used to test for chlorine gas

What is the positive result for the chlorine test?

Give the product of the following reaction Iron + chlorine →

Give the product of the following reaction magnesium + bromine →

When the metal halides dissolve in water they form

When the hydrogen halides dissolve in water they form

Tick all the boxes where a reaction would take place

As group 7 is descended _______________________

As group 7 is descended the tendency to gain an electron

As group 7 is descended the halogens become

From Fluorine to iodine the halogens become

Periodic table

What did Mendeleev leave in his periodic table?

In the modern periodic table the elements are in order of increasing

The number electrons in the outer shell of an element is equal to the

Which letter shows iodine in cyclohexane?

Use the results of the displacement reactions to place the halogens in order of reactivity from most reactive to least reactive. Note 1. the halide ions would have to be added as a salt such as KCl, KBr and KI rather than the individual ions Note 2. The potassium halide solutions are all colourless. Note 3. The final colour of the sample depends upon the halogen present only.
