Metals And Electrochemistry Flashcards
What are properties of a metal and what do they tell us?
What the metal is like and how it behaves.
What is thermal conductivity of a metal?
How easily heat can pass through the metal.
What is the electro conductivity of a metal?
How easily electricity can pass through a metal.
What is malleable?
Can be shaped into thin sheets.
What is ductile?
Can be drawn into wires.
What is density?
Heavy for its size.
What is strength.
Can support a heavy weight without breaking.
Where do metals come from?
The earths crust in the form of metal compounds called metal ores.
What is an ore?
A naturally occurring metal compound.
How can metals at the top of the reactivity series be extracted?
Using electrolysis
.
How can metals at the middle of the reactivity series be extracted?
Heating with carbon.
How can metals at the bottom of the reactivity series be extracted.
With heat.
What is the reactivity of a metal?
A measure of how easily the metal enters into a chemical reaction with another substance.
What is the experiment to measure the reactivity of metal/oxygen?
Burns the brightest.
What is the experiment to measure metal/water?
Gives off bubbles of gas the fastest.
