Question 2

What are some properties of Group 1 elements?

Answer 2

They are shiny when freshly cut
Good conductors of electricity
They are all soft enough to cut with a knife

Question 3

Going down Group 1

Answer 3

Their density increases
Their melting point and boiling point decreases
Reactivity increases

Question 4

Why are Group 1 elements stored in oil?

Answer 4

Because they react rapidly with oxygen in the air or water

Question 5

What happens to the reactivity as you go down group 1?

Answer 5

It increases

Question 6

What happens to Group 1 elements in reactions?

Answer 6

They lose their outer electron

Question 7

Why is it easier for more reactive elements to lose their electron?

Answer 7

Because they can lose their outer electrons more easily as the outer shell is further away from the nucleus
