Structure of the Atom
This lies at the center of the atom
What is the nucleus?
This English chemist suggested that all matter comprised of indivisible and indestructible atoms with distinct masses and properties.
Who is John Dalton?
This Austrian-Irish Physicist formulated a wave equation the accurately calculated the energy levels of electrons in atoms.
Who is Erwin Schrodinger?
This British physicist showed that all atoms contain tiny negatively charged subatomic particles or electrons.
Who is J.J. Thomson?
This is a group of subatomic particles believed to be among the fundamentals constituents of matter.
What is a quark?
This lies between electrons
What is empty space?
This German theoretical physicist speculated that wrong distances in space and time are actually relative. They change depend on how fast you’re moving.
Who is Albert Einstein?
This English physicist made a fundamental discovery by proving the existence of neutrons- elementary particles devoid of any electrical charge.
Who is James Chadwick?
This French physicist introduced the idea that particles, such as electrons, could be described not only as particles but as waves.
Who is Louis de Brogile?
This German theoretical physicist scientist discovered the quantum theory and claims that different atoms and molecules can emit or absorb energy in discrete quantities only.
Who is Max Planck?
This is made out of protons and neutrons
What is a nucleus
This French chemist was grounded in the law of conservation of mass explaining matter was conserved during chemical changes.
Who is Antoine Lavoisier?
This famous Greek philosopher theorized that all material bodies are made of individual small atoms
Who is Democritus?
These people were awarded a Nobel prize for physics and they successfully isolated radioactive radium salts from the mineral pitchblende.
Who is Marie and Pierre Curie?
This Danish physicist had several contributions to understanding atomic structure and quantum theory Including his idea that electrons orbit the nucleus at fixed energy levels ”created his own model”
Who is Niels Bohr?
These have positive, negative, and neutral charges
What is proton, electrons, and neutrons?
This English scientist, known as the true father of electricity, is responsible for the discovery of electromagnetic induction, electrolysis and diamagnetism.
Who is Michael Faraday?
This American physicist discovered the elementary charge of an atom using the oil-drop experiment
Who is Robert Milikan?
This French physicist discovered spontaneous radioactivity and the first person to discover evidence of radioactivity.
Who is Henri Becquerel?
This type of particle accelerator is a type of compact particle accelerator which produces radioactive isotopes that can be used for imaging procedures.
What is a Cyclotron?
This physicist from New Zealand postulated the nuclear structure of the atom, discovered alpha and beta rays, and proposed the laws of radioactive decay. He also received a Nobel prize for Chemistry in 1908.
Who is Ernest Rutherford?
This Italian physicist was responsible for the creation of the world’s first nuclear reactor and received a Nobel prize for his radioactive elements produced by neutron irradiation.
Who is Enrico Fermi?
This American theoretical physicist was often known as the father of atomic bomb, as he created the atomic bomb.
Who was J. Robert Oppenheimer?
This German theoretical physicist formulated a type of quantum mechanics based on matrices, and proposed the “uncertainty relation”, setting limits for how precisely the position and velocity of a particle can be simultaneously determined.
Who is Werner Heisenberg?
This particle accelerator is known as the most powerful particle accelerator in the world. It boosts particles, such as protons, which form all the matter we know.
What is the Large Hadron Collider (CERN) ?
