Answer
Calcium is both an element and a pure substance.
Solution
To determine the correct classification of calcium, let's analyze the options provided:
1. **Heterogeneous mixture**: A heterogeneous mixture consists of different components that can be physically separated. Calcium is not a mixture; it is a pure substance.
2. **Both an element and pure substance**: Calcium is indeed an element, as it is found on the periodic table with the symbol "Ca." It is also a pure substance because it consists of only one type of atom.
3. **Homogeneous mixture**: A homogeneous mixture has a uniform composition throughout. Calcium is not a mixture; it is a pure element.
4. **Both a compound and pure substance**: A compound consists of two or more different elements chemically combined. Calcium is not a compound; it is a single element.
Based on this analysis, the correct answer is:
**Both an element and pure substance.**

Calcium is a chemical element, represented by the symbol "Ca" on the periodic table, and it exists in its pure metallic form. Elements like calcium are crucial in various biological processes, such as bone formation and muscle contraction, making them vital to both plants and animals. In everyday life, calcium is well known for its role in dairy products like milk and cheese, which are commonly consumed for their calcium content. Calcium-rich foods are essential for maintaining healthy bones and teeth, and many people take calcium supplements to ensure they get enough of this vital nutrient in their diets.
