C14 metals

Question 1

What is reactivity of metal linked to?

Answer 1

Understand that the reactivity of a metal is linked to its tendency to form positive ions and the ease of extraction of the metal.

Question 2

How to use displacement of a metal to determine reactivity?

Answer 2

To determine a metal’s reactivity using displacement, dip a piece of that metal into a salt solution of another metal and observe if a reaction occurs. If the metal displaces the other metal from its compound, the added metal is more reactive than the metal in the solution.

Question 3

How are metals extracted?

Answer 3

Know that most metal ores are the oxides of the metal, and that the extraction of metals always involves reduction processes

Question 4

What are the properties of transition metals?

Answer 4

.They are able to form stable ions in different oxidation states
.They often form coloured compounds
.They are often used as catalysts (as ions or atoms)
