This picture shows mixture because there is more than one element or compound and they are mixed but they are not joined together.

What is the periodic table and what does it show? Include a picture!

A periodic table is a tabular arrangement of the elements according to their atomic numbers so that elements with similar properties are in the same column. A periodic table shows the atomic numbers.

Try to find some examples of everyday compounds, and

say which elements were bonded together to make them

I couldn’t find any?

Try to find some examples of everyday mixtures,

and say which elements are mixed together

together to make them

• Milk is a mixture of water and oil, the oil is in very small droplets in the water.

• Orange Juice mainly contents of water and e.g. citric acid, put a drop of orange juice stand on a spoon, let the water evaporate and a yellowish/reddish powder will form.
