Exploring Molecules Through Simple Examples: Oxygen and Water

Welcome, curious minds! In this video, I will demonstrate how two simple molecules—oxygen and water—are formed by combining atoms using covalent bonds. But before we dive into these examples, I strongly encourage you to watch my separate video on the Amini Periodic Table. This innovative approach simplifies understanding atomic structures and their combinations into molecules, making today’s topic much easier to grasp.

Part 1: The Oxygen Molecule (O₂)

Let’s start with the oxygen molecule. Oxygen consists of two oxygen atoms bonded through a double covalent bond. Each oxygen atom has six valence electrons, and by sharing two pairs of electrons, they achieve a stable octet configuration.

Here’s the fascinating part:

• The double bond is formed by the overlap of a sigma orbital (2s) and a 2py orbital, creating a stable molecular structure.
• The pi bonds arise from the overlap of "p" orbitals, where unpaired electrons in each oxygen atom combine to share four electrons in total.

This double bond allows the oxygen atoms to stabilize while creating a nonpolar molecule, as both atoms have identical electronegativity, leading to a symmetrical electron distribution.

Oxygen’s molecular structure beautifully demonstrates how atoms can share electrons to achieve stability while maintaining balance in their properties.

Part 2: The Water Molecule (H₂O)

Next, let’s look at water—a molecule with unique properties due to its bonding arrangement.

• An oxygen atom forms covalent bonds with two hydrogen atoms by sharing its outer electrons.
• Oxygen, with its four electrons in the 2p orbitals, pairs with hydrogen atoms that each contribute one electron from their 1s orbital.

Here’s why water is extraordinary:

• Oxygen attracts the shared electrons more strongly than hydrogen, creating a partial negative charge around oxygen and a partial positive charge around hydrogen.
• This unequal charge distribution makes water a polar molecule, enabling it to interact with other polar molecules and ions.

Water’s polarity explains its high surface tension, strong cohesion, and incredible ability to dissolve various substances—properties that are vital for life.

These two examples—oxygen and water—highlight the versatility and practicality of the Amini Periodic Table in understanding molecular formation. By visualizing the shapes and bonds of atoms, this table enables us to create and explore molecules with ease.
