In the given paragraph a brief about the difference between element and compound is given.

Elements are made up of the same type of atoms and each element is made up of one atom, that is they cannot be broken down into any other substance. Each element is different from each other due to its properties, though some have the same physical properties but are different in chemical properties.  Elements can be classified as metals such as iron and silver, non-metals such as oxygen and hydrogen, and metalloids such as boron and silicon.

Compounds are a combination of one or more elements such as water and salt. Compounds can be easily broken down into components through a chemical process.

Hence, the correct answer is:

1. Elements

2. one

3. properties

6. non-metal

7. metalloids

8. Compounds
