The Ideal chain model is a polymer that is built up of ideal gas like monomers forming a chain having a fixed bond length. The monomers have zero excluded volume, so they are free to overlap with impunity. Given that, a snapshot of a configuration of an ideal chain having N bonds will look exactly like the the result of N steps of a random walk.

End-to-end vector[edit]

The end-to-end vector, \vec{R} is given by the sum of the individual bonds, i.e. \Sigma_{i=1}^N \vec{r_i}. The average of this vector will be zero.
