Há 2 dias · Atom, smallest unit into which matter can be divided without the release of electrically charged particles. It also is the smallest unit of matter that has the characteristic properties of a chemical element. As such, the atom is the basic building block of chemistry.

Há 2 dias · Atom - Nuclear Model, Rutherford, Particles: Rutherford overturned Thomson’s model in 1911 with his famous gold-foil experiment, in which he demonstrated that the atom has a tiny, massive nucleus.
Há 1 dia · In the Standard Model of physics, electrons are truly elementary particles with no internal structure, whereas protons and neutrons are composite particles composed of elementary particles called quarks. There are two types of quarks in atoms, each having a fractional electric charge.
Há 3 dias · Atom - Proton, Neutron, Nucleus: The constitution of the nucleus was poorly understood at the time because the only known particles were the electron and the proton. It had been established that nuclei are typically about twice as heavy as can be accounted for by protons alone.
Há 3 dias · Standard model of elementary particles: the 12 fundamental fermions and 4 fundamental bosons. Brown loops indicate which bosons (red) couple to which fermions (purple and green). Columns are three generations of matter (fermions) and one of forces (bosons).
Há 4 dias · Particle Accelerators: Peering into the Heart of Matter. Particle accelerators, like the Large Hadron Collider (LHC), are powerful tools used to study the fundamental particles of matter. These machines accelerate particles to extremely high speeds and energies, allowing scientists to collide them and study the resulting particles and interactions.
Há 4 dias · Wave-particle duality is the term for the fact that fundamental objects in the universe such as photons or electrons appear to exhibit aspects of either waves or particles depending on the experiment.
