What are everyday objects made of? Atoms! But how much space do atoms actually take up, both inside themselves and between each other? In this video, we'll explore the volume inside atoms and the space between them. We'll discover that atoms are mostly empty space, and that the arrangement of atoms determines whether something is a solid, liquid, or gas.
Let's look at the volume inside an atom. An atom consists of a tiny, dense nucleus at the center, containing protons and neutrons. Surrounding this nucleus is a vast region called the electron cloud, where electrons orbit. The most remarkable thing about atoms is that they are mostly empty space! To understand the scale: if the nucleus were the size of a pea, the entire atom would be about the size of a football stadium. This means that the volume inside an atom is primarily empty space where electrons are likely to be found. The electron cloud defines the atom's size, but it's mostly just empty space with a few tiny electrons moving around.
Now let's explore the volume between atoms. The space between atoms varies greatly depending on the state of matter. In solids, atoms are tightly packed in fixed positions, with minimal space between them. They can only vibrate in place. In liquids, atoms are less tightly packed and can move around freely, sliding past each other. This creates more space between atoms than in solids. In gases, atoms are very far apart and move randomly at high speeds, resulting in large amounts of space between them. The forces between atoms, called intermolecular forces, determine how close atoms can get to each other in different states of matter.
Let's compare the empty space inside atoms versus the space between atoms. Inside atoms, there's mostly empty space with electrons orbiting a tiny nucleus. Between atoms, the amount of empty space varies by state of matter. In solids, there are small gaps between tightly packed atoms that can only vibrate in place. In liquids, there's moderate space allowing atoms to flow past each other. In gases, there's vast empty space with atoms far apart, moving freely. It's amazing to think that the world around us is mostly empty space! Whether we're looking inside atoms or between them, what appears solid to us is actually mostly emptiness.
To summarize what we've learned: Atoms are mostly empty space, with a tiny nucleus surrounded by an electron cloud. To understand the scale, if the nucleus were the size of a pea, the entire atom would be about the size of a football stadium. The space between atoms varies greatly depending on the state of matter: minimal in solids, moderate in liquids, and vast in gases. Intermolecular forces determine how close atoms can get to each other in different states. The most amazing realization is that the world around us is mostly empty space, both inside and between atoms! What appears solid to our senses is actually mostly emptiness when we look at the atomic level.
