The chi-square distribution's shape changes based on the degrees of freedom; it becomes more symmetric as the degrees of freedom increase. It is not negatively skewed (it is positively skewed, especially at lower degrees of freedom), and it does not have two sets of degrees of freedom as described; that characteristic applies to the F-distribution.
