Reactivity Flashcards
How are group 1 elements stored as a result of them being highly reactive to oxygen
They are stored in oil
How does the reactivity of group 1 metals increase
From top to bottom in a group
How do alkali metals react with water
They react with water to form metal hydroxides and hydrogen gas
How does lithium react with water
- reacts fast
- lithium floats on water
- no flame is seen
How does sodium react with water
- reacts very fast
- sodium melts and burns with a yellow flame
- the melted sodium moves around over the water
How does Potassium react with water
- reacts
- potassium melts and burns with a purple flame
What is the formula when alkali metals react with water
2X(s) + 2H2O(l) —> 2XOH(aq) + H2(g)
How do alkali metals react with oxygen
The react with oxygen to form metal oxides
What is the formula for when alkali metals react with oxygen
4X(s) + O2(g) —> 2X2O(s)
How do alkali metals react with halogens
They react with halogens to form metal halides
What is the formula for when alkali metals react with halogens
2X(s) + Y2(g) —> 2XY(s)

A light yellow toxic gas
What is chlorine
A light green poisonous gas
What is bromine
A brownish liquid that is highly volatile and toxic
What is iodine
A shiny black solid and forms a haze when it’s heated

What is the noble gases reactivity
Noble gases are inactive monatomic gases with completed outer energy levels
How do noble gases react with water
They are insoluble in water
What colour are noble gases
They are colourless
