Answer 23

Oxide

Question 24

What do non metal oxides and metal oxides give?

Metal oxides if reacted with water they make an alkaline solution. pH>7 Non metal oxides if reacted with water give an acidic solution. pH<7

Question 25

Name the group 7 halogens from the top

Answer 25

``` Fluorine Chlorine Bromine Iodine Astatine ```

Question 26

The halogens are diatomic. What does this mean?

Answer 26

The halogen atoms chemically join in pairs to form molecules. To represent one molecule for example we write F2, Cl2 and Br2.

Question 27

Do they get darker or lighter in colour as we go down the group? If so state each ones colour.

Answer 27

``` Darker Fluorine- pale yellow Chlorine- yellow green Bromine- orange brown Iodine- grey black ```

Question 28

Look at their states of group 7 halogens. Is there a pattern as we go down the group?

Answer 28

Yes there is a change of state from gases at the top to liquid to solid.

Question 29

What can you predict about astatine?

Answer 29

Physical state at room temp- solid Dark coloured solid possibly black The B.P would be higher than iodines

Question 30

Do the halogens get more or less reactive as you go down the group? What's the least reactive and most?

Answer 30

They get less reactive as you go down. Least- astatine Most- fluorine

Question 31

Are the halogens displacement reactions? Can you write out a general pattern?

Answer 31

Yes | More reactive halogen+compound of less reactive halogen>less reactive halogen+compound or more reactive halogen.

Why are the noble gases very un reactive?

Answer 35

Because they have a full shell of outer electrons giving them stable electron arrangements.
