Gavin Morgan 8/31/2015 Chapter 2 2-Point Notes The Nature of Atoms Atomic structure includes a central nucleus and orbiting electrons: 1. Danish physicist Niels Bohr created the model of the atom in 1913, which is still used today. 2. An atom?s mass is measured in daltons (6.02 x 1023 daltons = 1 g). A proton and neutron each way 1 dalton. Electrons determine the chemical behavior of atoms: 1. The position of an electron cannot be determined at any given time. 2. Orbitals are predictions where electrons are most likely to be found. Atoms contain discrete energy levels: 1. Electrons contain discrete energy levels which correspond to quanta.

Assignment 2 ? Chemical Bonds In this world there are many different kinds of living organisms. All organisms are composed of atoms, that bond together to make the necessary components of a living organism. There are three identified chemical bonds that are recognized, they are ionic bonds, covalent bonds and hydrogen bonds. All bonds are not created equal, just ask the electrons!

Chapter 2 Structure and Properties of Organic Molecules Organic Chemistry, 6th Edition L. G. Wade, Jr. Chapter 2 * Sigma Bonding Electron density lies between the nuclei. A bond may be formed by s-s, p-p, s-p, or hybridized orbital overlaps. => Chapter 2 Chapter 2 * Pi Bonding Pi bonds form after sigma bonds. Sideways overlap of parallel p orbitals. => Chapter 2 Chapter 2 * Multiple Bonds A double bond (2 pairs of shared electrons) consists of a sigma bond and a pi bond. A triple bond (3 pairs of shared electrons) consists of a sigma bond and two pi bonds. => Chapter 2 Chapter 2 * Molecular Shapes Bond angles cannot be explained with simple s and p orbitals. Use VSEPR theory.

?Opposite charges of polar molecules can interact to form hydrogen bonds. ?Often oxygen or nitrogen, but many other molecules. ?Weaker than covalent bonds but strong among water molecules 2.2 Vocabulary Isabella Hardman Period 7 9/2/14 ?Measures acidity ? U sually between 0 and 14 ? - 0 is very acidic (High H+) and 14 is in very basic (low H+) ?pH of 7 is neutral -Must be tightly controlled in organisms with buffers.-

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.

Chapter 6 The Chemistry of Life Atoms and Their Interactions Elements Carbon, hydrogen, oxygen, and nitrogen make up more than 96% of the mass of a human body. Atoms All nuclei contain: positively charged particles called protons (p+) particles with no charge called neutrons (n0). Electron cloud The region of space surrounding the nucleus contains extremely small, negatively charged particles called electrons (e-) This region of space is referred to as an electron cloud. Energy levels The first energy level can hold only two electrons. The second level can hold a maximum of eight electrons. The third level can hold up to 18 electrons. How many electrons are in fluorine?s 2nd energy level? How many protons are in an atom of fluorine? Isotopes
