What happens to the shape of the chi-square distribution as the degrees of freedom increase?

When there are only one or two degrees of freedom, the chi-square distribution is shaped like a backwards “J.” When there are three or more degrees of freedom, the distribution is shaped like a right-skewed hump. As the degrees of freedom increase, the hump becomes less right-skewed and the peak of the hump moves to the right. The distribution becomes more and more similar to a normal distribution.
