Group 1 Metals

Question 1

What are the alkali metals in group 1 ?

Answer 1

Lithium 
Sodium
Potassium 
Rubidium 
Caesium 
Francium 
They all have one outer shell which causes them to react similarly 
They are all soft and has low density

Question 2

Explain the trend in reactivity as you go down group 1

Answer 2

Increasing reactivity- the outer shell is more easily lost as the attraction between the nucleus and electron decreases because the electron is further away from the nucleus the further down you go

Lower melting and boiling points

Higher relative atomic mass

Question 3

What do alkali metals form with non metals ?

Answer 3

Alkali metals form ionic compounds with non metals

Question 4

When alkali metals react with water what do they produce ?

Answer 4

When alkali metals react with water they produce hydrogen gas

Question 5

What do alkali metals that react with chlorine produce ?

Answer 5

Alkali metals that react with chlorine produce salt

Question 6

What do alkali metals that react with oxygen produce?

Answer 6

Alkali metals that react with oxygen produces a metal oxide
