Alkalis and halogens

Question 1

What is the reactivity pattern in alkalis?

Answer 1

The further down the group the more reactive they get.

Question 2

What is the reactivity pattern in halogens?

Answer 2

They become less reactive the further down.

Question 3

What is the melting/boiling point pattern of alkalis?

Answer 3

They have lower boiling/melting points the further down you go

Question 4

What is the melting/boiling point pattern of halogens?

Answer 4

They have higher boiling/melting point the further down you go

Question 5

Why can’t halogens conduct electricity?

Answer 5

Because most of them are gases and are found in diatomic molecules covalently bonded, meaning they have no spare electrons.

Question 6

What compounds do transitional metals make?

Answer 6

Coloured compounds.

Question 7

What are the properties of transitional metals?

Answer 7

-Hard
-High boiling/melting points
-Good conductors of electricity/heat
-Aren’t as reactive
