Atomic Theory
Atomic theory is the scientific concept that all matter is made up of tiny, indivisible units called atoms. Each atom consists of a nucleus containing protons and neutrons, surrounded by electrons that orbit the nucleus. Protons are positively charged, electrons are negatively charged, and neutrons are neutral. Atoms combine to form molecules, which make up everything we see and touch. The arrangement and type of atoms determine the properties of a substance, such as its state (solid, liquid, gas) and its reactivity. This theory lays the foundation for understanding chemistry and the interactions between different materials.

Atomic theory is the scientific concept that everything in the universe is made up of tiny particles called atoms. These atoms are the building blocks of matter and combine in various ways to form molecules, which make up all substances, including solids, liquids, and gases. Each atom consists of a nucleus made of protons and neutrons, surrounded by electrons. This theory helps explain the properties of different materials, chemical reactions, and the behavior of elements. Developed over centuries, it has greatly enhanced our understanding of chemistry and physics, shaping modern science.

Atomic theory is the scientific idea that all matter is made up of tiny, indivisible units called atoms. Each atom is like a building block, and they combine in various ways to create everything around us, from water and air to plants and animals. Atoms consist of a nucleus, made of protons and neutrons, surrounded by electrons that move around it. This theory helps explain the structure of matter, chemical reactions, and the properties of different substances. Understanding atomic theory is fundamental to fields like chemistry, physics, and biology, influencing both technology and our comprehension of the universe.
