To determine which region is predominantly made of a single chemical element, we can analyze the given options based on their composition:

1. **Mantle:** The mantle is composed of silicate minerals that primarily contain elements such as silicon, oxygen, magnesium, and iron. It is not predominately a single element.

2. **Core:** The Earth's core is mainly composed of iron, with some nickel and lighter elements. This makes the core the region that is predominantly composed of a single chemical element, specifically iron.

3. **Atmosphere:** The atmosphere is a mixture of gases, including nitrogen, oxygen, argon, carbon dioxide, and water vapor. It is not made of a single element.

4. **Asthenosphere:** The asthenosphere, part of the upper mantle, is also composed of silicate minerals and is therefore not made of a single element.

5. **Crust:** The Earth's crust is composed of a variety of rocks that primarily contain silicon and oxygen, but like the mantle, it is not dominated by a single element.

### Final Answer
The region made predominantly of a single chemical element is the **core**, which is primarily composed of iron.
