Topic 1 Group 1 Elements Flashcards
What are group 1 elements known as
Alkali metals
What are the Alkali metals
Hydrogen
lithium
sodium
potassium
rubidium
cesium
francium
How many electrons are there on the outer shell of the alkali metals
1 which makes them very reactive and all have similar properties
Are alkali metals dense
Have low density and are soft
What are the trends for the alkali metals as they go down group 1
Increasing reactivity outer electron is easily lost as attraction between Nucleus an electron decreases as the electron gets further away
Lower melting and boiling points
Higher relative atomic mass
What do group 1 metals react vigourously with
Water
What is produced by group 1 metal reactions with water
Hydrogen gas and metal hydroxides
What do group 1 metals react vigourously with chlorine gas to create
Form white metal chloride salts
How are group 1 metals different to transition metals
React more vigourously with water, oxygen or group 7 elements
Much less dense strong and hard and have lower melting points
