Question 30

Why are Group 1 elements called Alkali Metals?

Answer 30

They are Metals that form Alkalis when they react with Water

Question 31

What is a Displacement Reaction?

Answer 31

A more reactive Element takes the place of a less reactive Element in a Compound

Question 32

Why doesn't KBr+ I2 react?

Answer 32

Iodine is less reactive than Bromine so won't displace it

Question 33

Balance KBr+ Cl2= KCl+Br2. Why is it a displacement reaction?

Answer 33

2KBr+ Cl2= 2KCl+ Br2 | Chlorine has displaced Bromine as its more reactive

Why is Fluorine more reactive than Chlorine?

Answer 34

Fewer shells, less shielding, easier to gain Electrons

Question 35

Why is Potassium more reactive than Lithium?

Answer 35

More shells, less shielding, easier to lose Electrons

Question 36

Why is Bromine less reactive than Chlorine?

Answer 36

More shells, more shielding, harder to gain electrons

Question 37

Why is Sodium less reactive than Caesium?

Answer 37

Fewer shells, less shielding, harder to lose electrons
