Alkali Metals (Group 1)

What are group 1 metals also called

Alkali metals

What are the properties of group 1 metals

Low melting and boiling points
Very soft

How reactive are group 1 metals

Very reactive

What ion does group 1 metals form

1+ ion

What happens when you go down group 1 metals

They get more reactive

Why do group 1 metals get more reactive as you go down

As you go down, the atom gets bigger→ electrons are further away from the nucleus→ attraction is weaker

What is produced when a group 1 metal mixes with water

Hydroxide and Hydrogen

How does lithium react with water

It moves, fizzes and decreases in size as it dissolves

How does sodium and potassium react to water

They do the same as lithium but they melt and form a ball.
Potassium even gets hot enough to ignite the hydrogen produced

How does rubidium and caesium react with water

They tend to explode when wet
