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)
How do alkaline Earth metals react with water
They form metal oxides and hydrogen
What is the formula for when alkaline earth metals react with water
X(s) + 2H2O(l) —> X(OH)2(aq) + H2(g)
How do alkaline earth metals react with oxygen
They form metal oxides
What is the formula for when alkaline earth metals react with oxygen
2X(s) + O2(g) —> 2XO(s)
How do alkaline earth metals react with halogens
The form metal halides
What is the formula for when alkaline earth metals react with halogens
X(s) + Y2(g) —> XY2(s)
How are halogens found in nature
Halogens are found in nature and diatomic molecules
What is fluorine
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
How do halogens react with hydrogen
The form hydrogen halides
What is the formula for when hydrogen reacts with a halogen
H2(g) + Y2(g) —> 2HY(g)
