Although they act like elementary particles,holes are not actually particles, but rather quasiparticles; they are different from the positron, which is the antiparticle of the electron. What is quasi physics? The termQuasi particles describes a physical concept,which treats elementary excitations in s...
A positron is an antimatter counterpart of the electron with a positive charge. A proton is a baryon particle found in the nucleus of atoms with a positive charge.
The scientific study of matter's characteristics and behaviour is known as chemistry.andare different from the normal vocabulary. It is a branch of natural science that examines the building blocks of matter, including the atoms, molecules, and ions that make up compounds and their composition, s...
The new chemistry and polymers presented at ICPA-12 are: understanding of chemical dynamics of positronium, wide applications of positronium as a useful probe to polymers, understanding of polymer surfaces, and improved understanding of complex chemical systems using positronium and positron probes.Y....

In chemistry, µ refers to the elementary particles muon and antimuon. A muon is similar to anelectron. However, its mass is about 207 times the mass of the electron. It is created when an electron collides with its antiparticle positron (e+). The collision creates a photon, which subs...
Electromagnetic radiation in the form of light is released when an electron loses energy. When an electron absorbs energy, it gets excited and moves... Learn more about this topic: Excited State in Chemistry | Definition & Example from
