While the present day surface of Venus is uninhabitable, the lower-cloud layer lies in the region of the atmosphere where pressure-temperature conditions are suitable for life (47–57 km altitude). This has led to suggestions of microbial life being a possible explanation for the existence of...
We soon zoom in on a silicon atom in the CPU. In theelectron cloud, the squiggles made out of arrows areFeynman diagrams. A Feynman diagram in the shape of a stick figure is saying "Sup?", a pun on the "Sup" particle (supersymmetric partner 'squark' to the Up quark) and an abbr...
1. What general principal is used in VSEPR theory to determine the shape of the electron cloud of a molecule? 2. Using the VSEPR theory, predict the molecular geometry of the following: a. GeH_4 b. Using the valence bond theory (and VSEPR), predict the molecular geometry of AsF5. ...

(the nucleus) with electrons in the vast empty space surrounding it. Most of the alpha particles shot straight through this electron cloud and were unaffected. The few that were deflected had been fired very near (or directly at) the nucleus, so their positive charge was repelled by the ...
Modern Atomic Theory | Overview & Models from Chapter 11 / Lesson 3 94K Learn about the modern atomic model. Understand the modern atomic theory and Schrodinger model. Discover what the modern atomic model is called, i.e., "electron cloud." Related...
Carbon isotope ratio (CIR), calculated as δ13C (per mil), can be used to estimate long-term water-use efficiency of leaves in natural vegetation26. The CIR was measured with an elemental analyzer (Flash EA 1112, Thermo Electron Corporation, Waltham, MA, USA) interfaced to an isotope rat...
Both the source and the drain regions are rich in electrons (because they're made of n-type silicon), but electrons cannot flow from source to drain because of the electron deficient, p-type material between them. If we apply a positive voltage to the transistor's two contacts, called ...
To explain why lone pair-lone pair repulsion is more than bond pair-bond pair repulsion, we can break down the reasoning into several steps:Step 1: Understanding Electron Pairs - In a molecule, electrons can be found in two for
Bohr Model: The Bohr model postulates that electrons are on stationary orbits. These orbits are concentric spheres around the nucleus. Electrons can move between the spheres, and each transition is associated with a specific energy. Answer and Explanation:1 ...
