- In chemistry, these are pure substances and consist of only one kind of atom. Meaning, the atoms have the same number of protons in their nuclei. Examples are silicon, oxygen, and aluminum.
COMPOUNDS
- These are substances that are formed by the combination of two or more different elements. Meaning, the atoms forming them are not only of one kind.
Looking at the photos, those with black and white circles which represent the atoms are the compounds as they are not uniform. Those that consist of only one kind have white or colorless atoms/circles.
