List of the First 20 Elements and their Physical Properties Atomic Radii (pm) of the First 20 Elements: - Atomic radii decreases when moving down a period‚ as the number of protons increases‚ which thence increases the effective nuclear charge. - Atomic radii increases when moving down a group‚ as the number of shells increases‚ which thence increases shielding. - The downward-sloping pattern on the above graph shows the decrease in atomic radii down a period‚ and the sudden jumps

Properties of Chemical Reactions Ms. Whitty‚ Science 10 Fiona Adams‚ November 1st‚ 2012 Introduction Chemical reactions are a part of our daily lives‚ from rusting metal to making bread to leaves changing colour in the fall. A chemical reaction is the process that occurs when two or more substances combine to produce a chemical change. When a chemical reaction takes place‚ the change is indicated by one or more qualitative properties. The colour or odor could change‚ gas could be produced

Chemical Properties Purpose: Investigating the chemical properties of pure chemical substances as well as exploring the physical properties of pure chemical substances Procedure: 1. I half-filled one well of a 24-well plate with 6M HCl and half-filled a second well of the 24-well plate with 6 M NaOH. I then sucked up these chemicals into their labeled pipets. I then set aside for later 2. I performed the following steps on each substance to be tested. I completed all tests of one substance

functional and chemical properties of eggs and other ingredients when making meringue. Chemical and Functional properties of eggs: Background information Eggs give a smoother texture to microwaveable dishes‚ frozen dishes are better to freeze. The yolk and the egg white cam be used in many different ways for different products of food. Eggs contain a lot of protein and a balance of other nutrition. Some producers require fresh eggs to be cooking with‚ it is easy to tell which eggs are old and fresh

Investigating the Properties of pH The manufacture’s claim is that Sensodyne toothpaste micro hardens tooth enamel to help protect against the effects of acid wear‚ helps stop the twinges of pain from sensitive teeth formulated with low abrasivity‚ neutral pH and gentle yet effective cleaning system. To find out if the manufactures claim on Sensodyne toothpaste is the correct level of pH. I expect the Sensodyne toothpaste to be a neutral pH level as the manufactures claim that this products

Department of Chemistry [Colligative Properties & Osmotic Pressure] Purpose : The experiment this week had two different purposes. The first is to teach us about freezing points. This lab was designed to show us the freezing point of a pure solvent‚ in comparison to a solvent in a solution with a non-volatile solute. The second goal of the experiment is to teach students about osmosis. In the experiment‚ we got to observe osmosis as well as understand dialysis
