What is an Element?

A chemical Element is one of the classes of substances that cannot be separated into simpler substances. It is also just one the atoms.

Hydrogen

As you can see there is only one type of atom in this example.

What is a compound? A chemical compound is a pure chemical

substance, which have two or more different chemical elements that can be separated into simpler substances by chemical reactions.

As you can see in the picture there are different kind of atoms that are joined together.

What is a mixture?

A mixture is what you get when you combine two chemicals in a way that no chemical reaction happens between the other atoms and you can separate them again.

As you can see in this picture that there are 2 chemicals but they aren’t bonded together.

What is the periodic table and what does it show?

The periodic table is A table of the chemical elements arranged in order of atomic number, in rows , so that elements with similar atomic structure appear in vertical columns.

Try to find some examples of everyday compounds, and say which elements were bonded together to make them

1. Salt - (Sodium Chloride) made up of sodium and chlorine.

2. Baking SODA - (Sodium Bicarbonate) made up of sodium, hydrogen, carbon and oxygen.

3. Washing Soda - (Sodium Carbonate) made up of sodium, carbon and oxygen.

THE END

BYEEEEE –ANA!
