Group 1 - The Alkali Metals - created from Mind Map

Seite 1

As you go down the metals become more reactive

the outer electron is more easily lost as it is further from the nucleus

They have lower melting and boiling points

Lithium, Sodium, Potassium, Rubidium and Caesium

all have one outer electron

form ionic compounds with non-metals

Keen to loose their outer electron and become 1+

produce white compounds that dissolve in water to form colourless solutions

React with water to produce hydrogen gas

They float and move around the surface, fizzing vigorously

They form hydroxides that dissolve in water to give alkaline solutions

2Na + 2H20
