Complex Ions Complex ion - ionic species consisting of a metal ion bonded to one or more Lewis bases Coordinate bond - bond formed when one anion/molecule donates a pair of electrons to another ion/molecule to form a covalent bond Ligand - a Lewis base bonded to the central metal ion of a complex ion Common Ligands (Lewis Bases): NH3, H2O, OH-, Cl-, CN- Inner coordination sphere - ligands that are bound directly to a metal via coordinate covalent bonds Counter ions - ions that balance the electrical charges of complex ions in coordination compounds Ex: [Ag(NH 3 ) 2 ] + + Cl - ?> [Ag(NH 3 ) 2 ]Cl Coordination compound - any compound that contains a complex ion Coordination number - identifies the number of electron pairs surrounding a metal ion in a

Florio 26 Nov. 2012 Jespersen, Hyslop, & Brady Chapter 10 Chemical Bonding & Molecular Structure VSEPR Theory Valence Shell Electron Pair Repulsion (VSEPR) Model: 1. e- pairs repel each other 2. e- pairs position themselves in 3D to minimize repulsion Molecules have well defined shapes based on their electronic structure. Molecular Structure: Shapes of molecules The shapes of molecules are derived from 5 different geometric structures that are classified by number of electron domains contained around the central atom. Two types of electron domains: Bonding domains (e- pairs in bonds) Nonbonding domains (e- pairs associated with a single atom)

Chemistry 1210: Introduction to General Chemistry Dr. Gina M. Florio 15 Nov. 2012 Jespersen, Brady, Hyslop Chapter 9 Chemical Bonding: General Concepts Ionic Bonds Ch. 9.2 Ionic bonds are the attraction between positive and negative ions in an ionic compound. e.g. NaCl An electron is transferred from the metal (Na) to the nonmetal (Cl): Ionic compounds form when metals and nonmetals react and they are held together by ionic bonds. Compounds (ionic and molecular) are formed due to a decrease (lowering) of the potential energy of system. Net energy change associated with the electron transfer reaction. So, why does NaCl (s) form at all? 2 Lattice Energy of Ionic Compounds Ch. 9.2 The energy needed to produce separated gaseous ions from one mole of the solid is the lattice energy:

Florio 05 November 2012 Jespersen, Brady & Hyslop Chapter 8 The Quantum Mechanical Atom Quantum Mechanics Ch. 8.1 The physics that describes objects with wave-particle duality is called quantum mechanics or quantum theory. In the late 1800?s, scientists discovered that electrons acted like tiny charged particles in some experiments and waves in others. Quantum mechanics accurately describes the structure and reactivity of atoms and molecules. Electromagnetic Radiation Ch. 8.1 Energy can be transferred as heat or as light. Electromagnetic radiation can be carried energy through space in the form of electromagnetic waves.

Campbell's Biology, 9e (Reece et al.) Chapter 4 Carbon and the Molecular Diversity of Life This chapter focuses on the chemistry of carbon and organic compounds. Students should be able to identify the nature of the bonds between carbon and other elements (nonpolar versus polar), the different types of weak bonds and interactions, the various types of isomers, the basic functional groups of organic molecules, and their relative solubility in water. The abiotic formation of organic molecules from inorganic molecules is important in the origin of life. Multiple-Choice Questions 1) The element present in all organic molecules is A) hydrogen. B) oxygen. C) carbon. D) nitrogen. E) phosphorus. Answer: C Topic: Concept 4.1 Skill: Knowledge/Comprehension

Campbell's Biology, 9e (Reece et al.) Chapter 2 The Chemical Context of Life This chapter presents basic chemical principles for understanding the chemical context of living organisms, from atomic structure to the nature of chemical bonds and an introduction to chemical equilibrium. These questions focus on elements most important to life or the study of life, including the elements that comprise organic molecules and important trace elements. Some isotopes are important in geologic dating and in biological tracer studies. How elements participate in forming different types of chemical bonds is essential to mastering subsequent topics on the behavior and properties of biological molecules, structures, and energy metabolism.
