Group 1 Metals

Question 1

How do group 1 metals react with water?

Answer 1

They produce a metal hydroxide and hydrogen

Question 2

What are the observations for the reaction of water

Answer 2

They fizz/hydrogen is produced
The metal floats and moves around on the water
The metal disappears

Question 3

What is the reaction for Lithium?

Answer 3

Fizzing
Lithium floats and moves around on the water
Lithium disappears

Question 4

What is the reaction for Sodium?

Answer 4

Fizzing
Sodium floats and moves around on the water
Sodium melts into a silver coloured ball
Sodium disappears

Question 5

What is the reaction for Potassium?

Answer 5

Fizzing
Potassium floats and moves around on the water
Catches fire with a lilac flame
Potassium disappears

Question 6

What happens when group 1 metals react with air

Answer 6

They oxidise

Question 7

Explain the trend in reactivity in group 1 metals in terms of electronic configurations

Answer 7

As you go down the group the outer electron lost from group 1 metals is further from the nucleus making it easier for it to be lost
