I don't understand the difference between each of these terms: atom, molecule, element and compound.
Can you help me ?

Thank you for your question!
First, let's define the terms:
• The atom is the smallest part of matter that can be obtained by dividing matter by chemical means. An atom is a particle.
• Element is a type of atom. There are more than a hundred kinds of elements, all of which are grouped within the periodic table. Groups of atoms of the same kind are also designated as elements.
• The molecule is a grouping of atoms linked together.
• Compound is a group of two or more types of atoms bonded together.
The difference between each of the terms is then the following:
• Atom-element: the atom designates only the particle itself, while the element designates a category of atoms, or even a group of atoms of the same sort.
• Atom-molecule: the atom designates a single particle, while the molecule designates two or more particles
• Atom-compound: the atom designates a single particle, while the compound implies the presence of two or more particles
• Element- molecule: the element designates a category of atoms or a group of atoms of the same kind, while the molecule designates a group of atoms linked together
• Element-compound: the element designates a group of atoms of the same sort, whereas the compound designates a group of bonded atoms of two or more kinds
• Molecule-compound: the molecule designates two or more particles bonded together, while the compound designates a group of bonded atoms of two kinds of elements or more
