OK its a fact that the universe is expanding but is the space between atoms expanding at the same rate too? and if not why did matter ie atoms and the space between them stop expanding shortly after the big bang?

There's no way to proove it, but it is generally assumed that space expands at the same rate everywhere, right down to the space inside an electron. Objects do not expand because they are bound together by forces, so all the newly created space ends up in the voids of the cosmic foam, surrounded by walls of galaxies. This moves the galaxies farther away from each other, but stars inside the galaxies are not affected by the expansion of space.
There is no evidence that matter has ever expanded. In very early times, atoms did not exist; earlier still, electrons, protons and neutrons did not exist. As the universe cooled, those particles condensed from the soup of more fundamental particles. Each species of subatomic particle has a fixed size, and there is no reason to think that size have ever changed.
In mainstream science, the expansion of space has something to do with dark energy; but no one knows what that is. For explanations of why and how space expands, you need to visit the New Theories section. We are not permitted to advertize our own new theories; they call it "evangelizing".

Phractality, it's a pleasure reading you
A very nice description. And I agree, we have alternative ideas in the 'New Theories' section. So take a look.
