Chapter 7 ? Periodic Properties of the Elements 7.1 Development of the Periodic Table ? Majority of elements discovered 1735-1843 ? Elements arranged to reflect trends in chemical and physical properties ? Periodic table arose from periodic patterns in electronic configurations o Valence orbitals o Trends in rows and columns ? Mendeleev and Meyer ? Modern periodic table 7.2 Effective Nuclear Charge Effective nuclear charge (Zeff) is the charge experienced by an electron on a many-electron atom. The effective nuclear charge is not the same as the charge on the nucleus because of the effect of the inner electrons. ? The electron is attracted to the nucleus, but repelled by electrons that shield or screen it from the full nuclear charge.

Cellular Transportation Josey Nelson Introduction Helps in maintaining homeostasis Two types: Passive Transportation No energy required Two main types High to low concentration Active Transportation Uses ATP for transportation Low to high concentration Diffusion The movement of particles from high concentration to low concentration Purpose: to reach equilibrium Osmosis is diffusion of water 3 major types Diffusion of ions Diffusion of molecules Osmosis (diffusion of water) Facilitated Diffusion Uses proteins to transport ions and molecules High to low concentration Requires Carrier Proteins No ATP (energy) Types of Solutions Hypotonic: a solution that contains higher water concentrations in solution

What is Dropbox? Dropbox is a free service that lets you bring all your photos, docs, and videos anywhere. Any file you save to your Dropbox will also automatically save to all your computers, phones, and even the Dropbox website. This means that you can start working on your computer at school or the office, and finish on your home computer. Never email yourself a file again! The Dropbox Folder After you install Dropbox on your computer, a Dropbox folder is created. If you?re reading this guide, then that means you had no problems finding your Dropbox folder :). This folder is just like any other folder on your computer, but with a twist. Any file you save to your Dropbox folder is also saved to all your other computers, phones, and the Dropbox website.

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.
