So everything is made of atoms, but what are they made of? Watch these videos to find out more about atomic structure.

1 = A
2 = b, helium, which can be broken down only into helium atoms by chemical means
c. copper, which is made of copper atoms
f. mercury, which can be broken down only into mercury atoms by chemical means
3 = A
To keep track of all of the elements, substances which can't be broken down into simpler substances by chemical means, we use something called the periodic table. There are usually questions about the periodic table on the GED test. It can be pretty complicated, but for the test you only need to know the basics. Check out these videos (one short and one a bit longer) to find out more.
Then, answer the questions below. If you're having trouble reading the periodic table in the picture, click here to see a bigger one on your computer screen.

1 = 3
1 = 3
2 = 2
2 = 2
3 = 3
3 = 3
4 = 4
4 = 4
5 = 1
5 = 1
So, everything is made of elements, which are made of atoms. But of course, nearly everything is a mix of different elements. This means that atoms of different elements can bond, or combine with other atoms.
