Compounds and their formation
Lesson details
Learning outcome
I can explain the difference between a compound and an element.
Key learning points
- A compound is made of two or more different elements chemically bonded through a chemical reaction.
- A compound may have different properties to each of the elements that it is made from.
Keywords
Chemical compound - A substance made by a chemical reaction where two or more different elements chemically bond together.
Chemical bond - A strong force that holds atoms together in a compound. A chemical bond takes lots of energy to overcome and break.
Common misconception
Compounds will have the same properties as the elements from which they are made.
Compounds usually have completely different properties from the elements from which they are made.
Teacher tip
It is best to use many examples of compounds and the elements from which they are formed. Sodium metal and chlorine gas are both dangerous and toxic to humans, however sodium chloride is added to food making, this a good example to use.
