C3 - Group 1: Alkali Metals Flashcards
Why does reactivity increase as you go down Group 1?
The outer electron is more easily lost as it is further from the nucleus.
What properties do the Group 1 metals have? [2]
Low melting/boiling points.
Low density.
List the elements in Group 1.
Lithium, sodium, potassium, rubidium, caesium.
What ion do Group 1 metals form?
1+ ion.
What bond type do Group 1 metals form and why?
Ionic.
They want to lose their outer electron.
What do Group 1 metals produce?
White compounds that dissolve in water to form colourless solutions.
What does the reaction between Group 1 metals and water produce?
Hydrogen gas.
What do you see when Group 1 metals react with water? [3]
Floating.
Moving.
Fizzing.
What happens to reactivity as you go down Group 1?
The elements become more reactive.
