C4.1.1 Group 1

Question 1

What are group 1 metals also known as?

Answer 1

Alkali metals

Question 2

Name some characteristics of Group 1 Metals

Answer 2

They are very reactive. They are very shiny and silvery. They are quite soft and can easily be cut with a knife. Low density and low melting points

Question 3

Definition of reactivity

Answer 3

How easily a element can gain/lose electrons to form a full outer shell

Question 4

Explain the pattern of reactivity in Group 1

Answer 4

As you go down Group 1, the atoms get bigger. The distance between the outer electron and the nucleus is greater. This means the electrostatic forces of attraction between the nucleus and the outer electron decreases. This makes it easier to lose an electron to acquire a full outer shell

Question 5

Does the melting point increase or decrease as you go down the group?

Answer 5

The melting point decreases as you go down Group 1

Question 6

Name the elements in Group 1

Answer 6

Lithium,Sodium,Potassium,Rupid,Caesium

Question 7

Do Group 1 metals react with water

Answer 7

Yes, they react readily with water
