This page explores some of the most fascinating and important molecular structures known to science. Use the links below to learn more. Please note that this page is…

  • Elements of the Periodic Table

    The periodic table is one of the most iconic and useful tools in chemistry. It is a tabular arrangement of all known chemical elements, organized by their atomic structure and chemical properties. The table is widely used to understand the behavior and relationships of different elements, and has been an important foundation for the development…

  • Electrons

    Electrons are subatomic particles that play a fundamental role in the structure and behavior of matter. Some key characteristics include:

  • Bosons

    Bosons are one of the two fundamental classes of particles in the universe, the other being fermions. They are distinguished from fermions by the fact that they obey Bose-Einstein statistics, which means that any number of bosons to occupy the same quantum state. One of the most famous examples of a boson is the photon,…

  • Compton Scattering

    Compton scattering is a fundamental process in quantum mechanics that describes how photons and electrons interact with each other. Discovered by Arthur Holly Compton in 1923, Compton scattering provided strong evidence for the particle nature of light and was a crucial component in understanding the behavior of radiation. Compton scattering occurs when a photon collides…

  • Absorption, Photon

    Photon absorption refers to the process by which an atom or molecule absorbs a photon and makes a transition to a higher energy level. This concept is at the heart of quantum physics and has a wide range of applications in various fields, including chemistry, biology, and materials science. (Please note that this process is intimately…

  • Acceleration

    Acceleration is one of the most fundamental concepts in physics and is a measure of how an object’s velocity changes over time. It is a vector quantity, meaning it has both magnitude and direction. It is calculated as the rate of change of velocity. In other words, acceleration tells us how quickly an object is…

  • Chapter 10: Free Fall Motion

    10.1 Introduction to Free Fall Motion Free fall is a type of motion experienced by objects that are falling under the influence of gravity. It occurs when an object is dropped from a height or is projected upwards and then falls back to the ground due to the force of gravity. 10.1.1 Definition of Free…

  • Chapter 6: Constant Acceleration

    6.1 Introduction to Constant Acceleration Motion Constant acceleration is an important concept in physics that describes the motion of an object that experiences a steady (unchanging) increase or decrease in velocity over time. This type of motion is also known as uniformly accelerated motion, as the object’s velocity changes by a constant amount during each…
