The mantle is chiefly made of ammonia, water and methane. One the other hand, the core is made of iron, nickel and various silicates.
Neptune is made up of an outermost layer the atmosphere. This forms 5-10% of the planet's mass, and extending up to 20% to its core. Neptune's atmosphere is about 80% hydrogen, 19% helium, with trace amounts of other ices, like methane, ammonia and water ice.
