Spicy Groups Flashcards
Metals
Form positive ions
On the left hand side of the periodic table
Non-metals
Form positive/ negative ions
On the right hand side of the periodic table
Properties of metals
Strong
Malleable
Can conduct heat and electricity
High boiling and melting points
Properties of non-metals
Brittle
Dull
Don’t conduct electricity (generally)
Low density
Properties of transitional metals
Conductors of heat and electricity
Dense
Strong and Shiny
Often form coloured compounds
Alkali metals
Group 1
They are extremely reactive (1 electron on the outer shell)
Soft
Low density
Why does group 1 increase in reactivity
Outer electron is more easily lost due to weaker electrostatic forces of attraction between the positive nucleus and negative electron
Alkali metal reaction with water
Effervescing
Produce hydrogen gas and metal hydroxides
Alkali metal reaction with chlorine (gas)
Form white metal chloride salts
Alkali metal reaction with oxygen (gas)
Form metal oxide
Alkali metal in comparison to transition metals
More reactive
Less dense strong and hard
Lower melting points (not mercury)
What colours is fluorine (gas)
Yellow
What colour is chlorine (gas)
Green
What colour is bromine (liquid)
Red Brown
What colour is iodine (solid)
Dark Grey or purple vapour
Why is group 7 less reactive the further down the periodic table :0
It’s harder to gain an electron due to weaker electrostatic forces of attraction between the positive nucleus and negative electron
What is group 0’s colour
Colourless :0
