## Chemistry Section 15

- The ground state is the lowest energy state of an atom, while excited states have higher energy.
- Absorption and emission spectra are used to identify the elements present in a sample.
- Electromagnetic radiation is emitted when electrons transition from higher energy levels to lower energy levels.
- The principal quantum number (n) specifies the energy level of an electron.
- The angular momentum quantum number (l) determines the shape of an orbital.
- The magnetic quantum number (m_l) specifies the orientation of an orbital in space.
- The spin quantum number (m_s) describes the spin direction of an electron.
- Quantum mechanics is the branch of physics that describes the behavior of particles at the atomic and subatomic scale.
- The SchrÃ¶dinger equation is a fundamental equation in quantum mechanics that describes the wave-like behavior of particles.
- Wave functions are used to describe the probability distribution of finding a particle in a particular state.
- The probability of finding an electron in a specific region of space is given by the square of the wave function, known as the electron density.
- Quantum mechanics provides a probabilistic description of particles, unlike classical mechanics which provides deterministic predictions.
- The uncertainty principle, proposed by Werner Heisenberg, states that the position and momentum of a particle cannot be simultaneously known with high precision.
- The wave-particle duality of light and matter is a fundamental concept in quantum mechanics, meaning that particles like electrons can exhibit both wave-like and particle-like behavior.
- The double-slit experiment demonstrates the wave-like behavior of particles and the role of observation in collapsing the wave function.
- Superposition is the principle that states a particle can exist in multiple states simultaneously until observed.
- The concept of entanglement in quantum mechanics suggests that particles can become correlated in such a way that the state of one particle instantaneously affects the state of another, even at a distance.
- Quantum tunneling is a phenomenon where particles can pass through energy barriers that classical physics would predict as impassable.
- Quantum mechanics has led to the development of many technologies, including lasers, transistors, and quantum computers.
