Where are metals usually found?
In the ground
What can metals react with?
They can react with the substances and the environment around them Such as air water and acids
in a word equation, what are the chemicals called that was that you start with and end with?
you start with the reactants and you end with the products
How can a equation be balanced?
By putting numbers in front of the formulas, you cannot change the actual formula itself
Put these in most reactive to least reactive:
Lithium,calcium, zinc, iron magnesium, silver,sodium, gold,potassium, copper.
Potassium, sodium, lithium, calcium, magnesium, zinc, iron,
copper, silver,gold
How can the reactivity of metals be compared?
By the observations of their reactions with acid
What is the metal and acid equation?
Metal plus acid ➡️salt plus hydrogen
What is oxidation?
adding oxygen to an equation
What is reduction

-liquid/gas
-light
-insulator
-brittle
finish the equation:
metal + acid➡️
➡️salt + hydrogen
On the periodic table,are group 1 metals more reactive going up or down?
They are more reactive the further down they go
