Particles and antiparticles are indeed related to each other, but they have opposite properties in certain respects. Let's explore the concept further:
Particles: In the realm of particle physics, particles are the fundamental constituents of matter and energy. They can be classified into various types, such as electrons, protons, neutrons, quarks, and many more. Particles have specific properties such as mass, charge, and spin, which determine their behavior and interactions.
Antiparticles: For every particle, there exists a corresponding antiparticle. Antiparticles have the same mass as their corresponding particles but possess opposite electric charge. For example, the antiparticle of an electron is called a positron, which has the same mass as an electron but carries a positive charge instead of a negative one.
Opposite properties: Particles and antiparticles exhibit opposite properties when it comes to certain fundamental quantities. These properties include electric charge, baryon number, lepton number, and other quantum numbers associated with different types of particles.
Interaction: Particles and antiparticles can interact and annihilate each other. When a particle and its corresponding antiparticle collide, they can mutually destroy each other, converting their mass into energy according to Einstein's famous equation E=mc². This process is known as annihilation. The resulting energy can then potentially produce other particles or be observed in different forms.
However, it's important to note that not all particles have antiparticles. Some particles, such as photons (particles of light), are their own antiparticles. These are called "neutral" particles.
In summary, particles and antiparticles are related to each other through opposite properties such as charge. While they have the same mass, they differ in terms of charge and certain quantum numbers. Their interaction can lead to annihilation, converting their mass into energy.
