Reactivity Series definition
Reactivity Series definition
A list ranking metals from most to least reactive
Metal reactivity trend moving down a group
Metal reactivity trend moving down a group
Increases (more reactive)
Metal reactivity trend moving right to left across period
Metal reactivity trend moving right to left across period
Increases (more reactive)
Most reactive naturally occurring metal
Most reactive naturally occurring metal
Cesium (Cs)
Most reactive metal overall
Most reactive metal overall
Francium (Fr)
Example of least reactive metal
Example of least reactive metal
Platinum (Pt) or gold (Au)
What metal reactivity relates to
What metal reactivity relates to
Ability to lose electrons and form positive ions
How Na and K react with water
How Na and K react with water
Explosively
How gold reacts with water or dilute acids
How gold reacts with water or dilute acids
Does not react
How Reactivity Series was determined
How Reactivity Series was determined
Observing reactions with water and acids
Products when top series metals react with water/acids
Products when top series metals react with water/acids
Hydrogen gas and a salt
Reaction behavior at bottom of Reactivity Series
Reaction behavior at bottom of Reactivity Series
Little to no reaction
Why non-metals like C and H included in series
Why non-metals like C and H included in series
To determine metal extraction from ores
Relationship: position in series and reaction vigor
Relationship: position in series and reaction vigor
Higher in series = more vigorous reaction
