    It depends upon its history. The outermost layer could be a mix of hydrogen and helium with a smattering of heavier elements like the Sun.

So a surface layer mostly hydrogen with a helium layer or core underneath. If sufficiently massive there would be a carbon core not helium.

    Since black dwarfs are just very old white dwarfs the composition of white dwarfs applies:
