Reactivity series Flashcards
What is the reactivity series
the arrangement of metals in the descending order of their reactivities.
What is the reactivity of metal related to?
Metals react with other substances forming positive ions. The reactivity of a metal is related to its tendency to form positive ions. Metals which form positive ions more easily are more reactive
What is the product of metals reacting with oxygen?
Metal + Oxygen —-> Metal Oxide
Physical properties:
- appearance
- Texture
- Color
- Odor
- Melting / boiling point
- Density
- Conductivity
What is a physical change?
A physical change alters the form of
the substance, and does not change to another substance
Chemical Properties
- Flammability
- Tendency to undergo a reaction with other substances (reactivity)
What is a chemical change?
When a substance undergoes a chemical change,
it is changed into a different substance with different properties.
What are some signs of a chemical change?
Colour change
Production of gas
light is released
temperature change
What is the product of metal reacting with water?
Metal + Water —-> Metal hydroxide + Hydrogen gas
