What is the Difference Between Molecule of Element and Molecule of Compound?

The main difference between a molecule of an element and a molecule of a compound lies in the types of atoms they contain and how they are bonded together. Here are the key differences:

• Molecule of an element: A molecule of an element is formed when two or more atoms of the same element combine together. These atoms share electrons and are held together by covalent bonds. Examples of elements that can form molecules include hydrogen (H₂), oxygen (O₂), and nitrogen (N₂).
• Molecule of a compound: A molecule of a compound is formed when two or more atoms of different elements combine together. These atoms can be bonded through various types of chemical bonds, such as ionic bonds, covalent bonds, or metallic bonds. Compound molecules are always made of two or more elements.

In summary, a molecule of an element contains two or more atoms of the same element, while a molecule of a compound contains two or more atoms of different elements, bonded together through various types of chemical bonds.

Comparative Table: Molecule of Element vs Molecule of Compound

Here is a table comparing the differences between a molecule of an element and a molecule of a compound:

A molecule of an element is formed when atoms of the same element combine, such as H2 (hydrogen) or N2 (nitrogen). On the other hand, a molecule of a compound is formed when atoms of different elements combine, like H2O (water) or NaCl (sodium chloride).
