PPT-Energy and Electrons

WaveParticle Duality JJ Thomson won the Nobel prize for describing the electron as a particle His son George Thomson won the Nobel prize for describing the wavelike nature of the electron The electron is a particle.

What . is your favorite thing we’ve done this semester and why?. Vladimir . Mikhailov. NRNU MEPHI , Moscow, Russia. For PAMELA collaboration . ICPPA 2015, PAMELA workshop, 9 October 2015. PAMELA detectors. GF: 21.5 cm. 2. sr Mass: 470 kg. Size: 130x70x70 cm. Review. Electrons are the negatively charged part of the atom. Electrons are found in . orbitals. around the nucleus. We write the electron configuration of the element to see the different . orbitals. If we can’t see the electron, and it has no mass, then why is it important?. BONDING!. Electrons are the only particle that participate in bonding between atoms.. How do we know when and how things will bond, though?. Noble gases and diatomic elements (except bromine, and iodine). These all have only London dispersion forces. . These are very weak intermolecular forces.. They all have very low melting points, obviously since they are gases.. Ions. Valence electrons are the electrons that are found in the outermost shell of an atom.. Valence electrons participate in bonds (can move from one atom to another). . Review…. 1. 2. 3. 4. 5. 6. Chapter Big Idea . The atoms of each element have a unique arrangement of electrons.. Section 1: Light and Quantized Energy. Essential Questions & Vocabulary. How do the wave and particle natures of light compare?. Bell work for November 25, 2018. Directions-Many Scientific words, such as . bond. , also have everyday meanings. Use context clues to write your own definition for each meaning of the word . bond. . Cellular Respiration . Cells harvest chemical energy stored in molecules and use this to generate ATP. . Organic compounds store energy in their arrangements of atoms.. Catabolic (releases energy). Exergonic. use flame tests to provide evidence . that energy is absorbed or released in discrete units when electrons move from one energy level to another . explain how flame tests provide evidence . that energy is absorbed or released in discrete units when electrons move from one energy level to another . •Explain the factors that influence ionisation energies.. •Predict the number of electrons in each shell as well as the element’s group, using successive ionisation energies.. Key Words:. Electrons, first ionisation energy, successive ionisation energies, electron shielding. . Three rules:. electrons fill orbitals starting with lowest n and moving upwards;. The order is: 1s, 2s, 2p, 3s, 3p, 4s, 3d, 4p, 5s, 4d etc.. Orbital Diagram. The . electron configuration. of an atom is a shorthand method of writing the location of electrons by sublevel.. Fermi liquid theory.  (also known as . Landau–Fermi liquid theory. ) is a theoretical model of interacting . fermions.  that describes the normal state of most . metals.  at sufficiently low . the ionic . charge would be . 3–, [(7+) . + . (10–) . = . 3–]. . The ion, written as . N. 3–. , . is . the . nitride. . ion.. b. . The . element with 20 protons is calcium. In an ion of calcium with 18 electrons, .
