Calculate for each balanced redox reaction and determine if the reaction is spontaneous as written.
Sunday, August 28, 2016 Chapter 1: Chemical Bonding Organic vs. Inorganic • Organic: Has carbon • Inorganic: No carbon Review • Atom: The smallest unit of a substance. 3 Atomic Number • Proton: Positive charge Symbol Li • Neutron: No charge 6.941 Atomic Mass • Electron: Negative charge Electrons • Take up the majority of the atom’s volume • In the electron cloud • Important for Bond Formation: • Core electrons Valence electrons • • Electrons have kinetic energy which helps keep them away from the nucleus The Distribution of Electrons in an Atom • Electrons lie in shells that surround the nucleus • Each shell contains subshells: 1. S 2. P 3. D 4. F 1 Sunday, August 28, 2016 • Atomic Orbitals: 1. S: 2 • “S” orbitals can hold 2 electrons 2. P: 6 • “P” orbitals can hold 6 electrons 3. D: 10 • “D” orbitals can hold 10 electrons 4. F: 14 • “F” orbitals can hold 14 electrons What Orbitals Do The Electrons Occupy • Electron Configuration: The arrangement of electrons in the orbitals • Ex) Lithium (Li) 1s² 2s¹ • Rules 1. Aufbau
