Understanding Elements and Atoms: Basics of Matter and Subatomic Particles

This overview explores the fundamental concepts of elements and atoms, the building blocks of matter. Elements are unique substances that cannot be broken down by ordinary chemical methods, with 112 known elements, of which 92 occur naturally. Atoms, the smallest particles retaining these properties, are essential in understanding matter's structure. Comprising electrons, neutrons, and protons, atoms can be divided into smaller particles under certain conditions. This knowledge has profound implications in fields like nuclear energy and atomic research.

Presentation Transcript

  1. Elements and Atoms (pg. 27-29) By Megan Blosser Dominique Johnson and Shannon Painter

  2. Elements • A unique substances that can not be broken down into other simpler substances by ordinary chemical methods • Examples: oxygen, carbon, gold, iron • 112 known elements (113 to 116 are alleged) • 92 of them occur naturally while the rest are produced artificially

  3. Elements

  4. Atoms • The smallest particle that still retains its special properties • The basic building blocks of matter • The weird atom has Greek origins and means, incapable of being divided

  5. Atoms • Atoms are indescribably small • Are made of subatomic particles • Under special circumstances can be split into smaller particles • When split into smaller particles the elements loose their special properties • Man used the atom to create atomic bombs and harness the power of electricity through nuclear power

  6. Atoms • The atom consists of electrons, neutrons, and protons
