Section 14 - Groups in the Periodic Table

Question 1

Groups 1, 7 and 0 - Give two properties of the Group 1 metals

Answer 1

1) Good thermal and electrical conductivity

2) Malleable

Question 2

Groups 1, 7 and 0 - Explain why Group 1 metals are so reactive

Answer 2

It is easier for them to lose their one outer electron so they have stable full shells

Question 3

Groups 1, 7 and 0 - How many electrons do halogens have in their outer shells?

Answer 3

7 electrons

Question 4

Groups 1, 7 and 0 - Why can halogen displacement reactions be described as redox reactions?

Answer 4

Halogen displacement reactions are redox reactions because the halogens gain electrons and the halide ions lose electrons

Question 5

Groups 1, 7 and 0 - At room temperature, what colour are the Group 0 gases?

Answer 5

Colourless

Question 6

Groups 1, 7 and 0 - Why are balloons filled with helium able to float in the air?

Answer 6

Helium has a lower density than air

Question 7

Groups 1, 7 and 0 - Does the boiling point of Group 0 elements increase or decrease as you go down the group?

Answer 7

Increase
