What is the relationship between quantum mechanics and atomic theory?

Quantum mechanics is the framework that explains the behavior of particles at the atomic and subatomic levels, while atomic theory describes the structure and properties of atoms. Together, they provide a comprehensive understanding of matter.

Can you explain how quantum mechanics changed our understanding of atoms?

Certainly! Quantum mechanics introduced concepts like wave-particle duality and uncertainty, which challenged classical views of atoms as solid, indivisible units. It showed that particles can exist in multiple states and locations simultaneously.

What are some key experiments that support quantum mechanics?

Key experiments include the double-slit experiment, which demonstrates wave-particle duality, and the photoelectric effect, which shows how light can behave as both a wave and a particle.

How does quantum entanglement relate to atomic theory?

Quantum entanglement describes a phenomenon where particles become interconnected, such that the state of one instantly influences the state of another, regardless of distance. This challenges classical notions of locality and has implications for atomic interactions.

What are the practical applications of quantum mechanics in technology?

Quantum mechanics has led to advancements in technologies like semiconductors, lasers, and quantum computing, which rely on quantum principles to function.
