 [:)]

I start to think rubber-problem,,, by using atom-theory,,and i dont have answer to my question,,,only more questions,,,

Do we known how rubber-matter work?

How rubber-stretch,,that matter in the rubber,,,exactly work?

The bonds between atoms can stretch a bit and the angles can twist a bit. But the most important thing for elastic materials like rubber is that the long thin molecules can straighten out.

It's a name for the bit of space between the nuclei of two atoms where the electron density is higher. It's also what holds the atoms together to make molecules.
