Atomic Theory

The video tutorial explains the fundamental concept of atoms, which are the building blocks of matter, consisting of protons, neutrons, and electrons. It introduces John Dalton's atomic theory, which states that all matter is made of atoms, and describes the formation of compounds and chemical reactions. The video also covers the states of matter—solids, liquids, and gases—and their atomic arrangements. Additionally, it introduces the periodic table, highlighting elements like oxygen and gold, and explains how compounds like saltwater form without chemical change, unlike chemical reactions that rearrange atoms to create new substances, such as water.

Describe the arrangement of atoms in solids, liquids, and gases.
