Lesson AimsLesson Aims•To understand how to name simple compounds
You are now ready to meet REG and play a game of ELEMENT BINGO!
How well do you know the elements and their symbols?
Draw a simple grid of 5 boxes in a row like this one.
Write down the symbols for 5 of the first 20 elements in these boxes.
Make sure your neighbour hasn’t copied your 5 symbols.
Test your elements expertise with this true or false quiz.
An element is made up of only one type of atom.
All atoms are the same.
Each element has its own type of atom.
There are about 100 different elements so there are about 100 different atoms.

Test your elements expertise with this true or false quiz.
A substance that is not an element contains more than one type of atom.
The symbol for an element is always the first letter of its name.
The chemical symbol for the element carbon is O.
The same chemical symbols are used all over the world.

Fabulous formulaeA chemical formula can be very informative.
It shows the numbers and types of elements in a compound.What is the formula of the compound described by these compositions?
One copper to one oxygen
One carbon to two oxygen
One calcium to one carbon to three oxygen
CuO
CO2
CaCO3
Hydrogen and oxygen in the ratio 2:1 H2O
Carbon and hydrogen in the ratio 4:1 CH4
Potassium, nitrogen and oxygen in the ratio 1:1:3
KNO3
Elements and Compounds
It follows that compounds contain two or more types two or more types of atom.of atom.
The water molecule contains two hydrogen atoms bonded to one oxygen atom, so the formula is
H2O.
Elements are materials made up of one type one type of atom only.of atom only. Hydrogen molecule
contains two hydrogen atoms bonded together, so
the formula is H2.
Naming Simple compounds. It is easy to name simple compounds of metals and non-metals.
1. Write down the name of the metal2. Write down the name of the non-metal but
change the ending to “ide.”

Naming Simple compounds.
Naming more complicated Compounds
Many compounds contain more than two elements. Naming them can get complicated but for those containing two elements plusplus oxygen the name ending usually changes to –ate.–ate.
