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.

An Analysis of Bacterial DNA Extracted from Water near Farms Previous research has suggested that pharmaceutical levels on farms have increased over time. Due to this, the pharmaceuticals can pollute the soil and water in the area surrounding the farm. Other research has showed that many pathogens have re-emerged on many farms. A gap exists in the literature, however, as to how these pathogens have re-emerged. The purpose of this study is to compare the bacteria found in various water sources on farms to the ?common? form of the bacteria. This could possibly allow new medication and vaccines to be formed quicker based on the strains found on various farms. Procedures: Collect bacterial samples from various sources Runoff Rivers Manure Troughs Culture the bacteria on agar

Summary of AP Bio Study Book: Barron?s AP Bio Chemistry Section The biochemistry section includes the following subjects: Atomic Structure, Bonding, Polar and Nonpolar Molecules, Hydrophobic and Hydrophilic Substances, the Properties of Water, Isomers, Organic Compounds, Energy, Enzymes, and Metabolism. Atomic Structure All atoms consist of three subatomic particles: neutrons, protons, and electrons. An atom in the elemental state always has a neutral charge because the number of protons equals the electrons. Isotopes are atoms that have the same atomic number but have a different mass because they have more or less protons than usual.

Chapter 3 Biology Outline- ?Water and the Fitness of the Environment? The polarity of water molecules results in hydrogen bonding Water is more extraordinary than people thing because water is everywhere. The unequal ?v? shape of a water molecule makes it a ?polar molecule?. Polar molecules have a positive charge on one side of the molecule and a negative charge on the other side. The polar molecules are attracted to each other (they are like magnets) and that is why water always forms droplets and stays together. Four emergent properties of water contribute to Earth?s fitness for life Cohesion Water molecules stick together due to hydrogen bonding. Cohesion contributes to the transportation of water and dissolved nutrients going against gravity in plants.

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.
