This is a drawing showing the composition of the interior of Jupiter.

The Composition of Jupiter's Interior

The composition of Jupiter's interior is mostly the simple molecules hydrogen, in the form of liquid.

Under the cloud layers, when the pressure of the interior becomes high enough, the hydrogen of which Jupiter is made transforms to liquid hydrogen, which gradually transforms further to liquid metallic hydrogen.

The core of Jupiter is made out of heavier, rocky and metal elements such as silicates and iron.
