Quiz:

Comparing the reactivities of group 1 and group 7

This quiz will test your understanding of group 1 and group 7 elements. It will also contain some revision questions from previous lessons in this topic.

Q1.Which famous scientist discovered the neutron?

1/9

Q2.What charged ion do group 2 metals form?

2/9

Q3.Below is a chromatogram after a mixture has been separated by chromatography. How many dyes are there in the mixture?

3/9

Q4.Describe the reactivity of group 1 metals as you go down the group.

4/9

Q5.Describe the reactivity of group 7 elements as you go down the group.

5/9

Q6.Describe what happens when a group 1 metal reacts.

6/9

Q7.Describe what happens when a group 7 element reacts.

7/9

Q8.True or false: Group 1 the reactivity of group 1 metals increases as you go down the group because there are more shells, and therefore the outer shell electron is further away from the nucleus. There is also more electron shielding. This means that it is easier for the positive nucleus to attract an electron to the outer shell.

8/9

Q9.True or false: Group 7 the reactivity of group 7 elements decreases as you go down the group because there are more shells, and therefore the outer shell is further away from the nucleus. There is also more electron shielding. This means that it is easier for the positive nucleus to attract an electron to the outer shell.
