Title of the Course: “ Chemical Bonding ”. Instructor: Dr. Sumita Naskar Hazra Department of Science and Humanities RTC Institute of Technology, Ormanjhi , Ranchi. Course Objectives T o understand the concept of Lewis structure of molecules

Chemical Bonding and Molecular Structure (Chapter 9). Ionic vs. covalent bonding Molecular orbitals and the covalent bond (Ch. 10) Valence electron Lewis dot structures octet vs. non-octet resonance structures formal charges VSEPR - predicting shapes of molecules

Chemistry. Matter. Organisms are composed of matter Matter is anything that takes up space and has mass Matter is composed of chemical elements Matter is found on the Earth in three physical states Solid Liquid Gas. States of Matter.

Lecture 21: Chemical Bonding. Reading: Zumdahl 13.1-13.3 Outline Types of Chemical Bonds Electronegativity Bond Polarity and Dipole Moments. Chemical Bonds.

Stable Isotopes. Most elements come in several isotopes. The relative abundance of these isotopes can provide information on ONE of source material, original chemical reactions, post-origin chemical reactions, temperature of reaction if the other variables are sufficiently constrained.

Bonding and Molecular Structure. Goals: Understand the differences between ionic and covalent bonds . Draw Lewis electron dot structures for small molecules and ions.

Students who haven’t passed the safety quiz. Understanding “periodicity”. Trends within a period what is changing? what is constant? Trends within a group what is changing? what is constant?. 11 Na. 12 Mg. 11 Na. 19 K. First Ionization Energy (first ionization potential)

Warm Up. Draw and label the parts of an atom. Using the terms: proton, neutron, electron, nucleus, electron cloud. Biochemistry. Chapters 2 & 3. Matter. Occupies space & has mass Mass: any quantity of matter an object has All matter is made up of tiny particles called atoms

Chemistry 11 Chemical Bonding. Electronegativity – the tendency of an atom to attract electrons from a neighbouring atom. . Get lost, loser!. Hey! I find your electrons attractive !. Electronegativity increases as you move from left to right. .

Stable Isotopes. Most elements come in several isotopes. The relative abundance of these isotopes can provide information on ONE of source material, original chemical reactions, post-origin chemical reactions, temperature of reaction if the other variables are sufficiently constrained.

Chapter 2. The Chemical Basis of Life. Basic Chemistry. Matter, Mass, and Weight Matter : Anything that occupies space and has mass Mass : The amount of matter in an object Weight: The gravitational force acting on an object of a given mass Elements and Atoms

CHEMICAL BONDING. Chemistry I – Chapter 8 Chemistry I Honors – Chapter 12. Cocaine. SAVE PAPER AND INK!!! When you print out the notes on PowerPoint, print "Handouts" instead of "Slides" in the print setup. Also, turn off the backgrounds (Tools>Options>Print>UNcheck "Background Printing")!.

Fundamentals of crystal chemistry. Mineralogy Carleton College. Crystal Chemistry. As we have been discussing for the last week, crystals, and thus minerals, are made up of a 3-dimensional array of atoms arranged in an orderly fashion. . Crystal Chemistry.

1.12 Electron Waves and Chemical Bonds. Models for Chemical Bonding. The Lewis model of chemical bonding predates the idea that electrons have wave properties. There are two other widely used theories of bonding that are based on the wave nature of an electron. Valence Bond Theory
