Chemistry Essay On Metals Iraj Malik 12/10/2012 MYP-5 The International School A metal is defined as a chemical element that is malleable and ductile‚ usually solid‚ has a characteristic luster‚ and is a good conductor of heat and electricity‚ e.g. copper or iron. Metals form oxides that are basic‚ they are good reducing agents and metals have lower electro negatives.There are many properties of metals. The chemical properties are that they can combine together with other metals to form am alloy

without metal. The metals we use in our houses are mostly for keeping them sturdy. Though there is one problem we have when it comes to metals. That problem is that they rust. Metals rust when they are in contact with oxygen‚ and water. They rust much faster when they are in contact with salt water‚ and acid rain. We chose to see what would happen to various metals when they contacted with salt water. When the electrons move around in the salt water‚ it causes the metals to rust. The metals we chose

Experiments with Metals and Ions of Metals Introduction Metals are similar in their physical properties in general‚ but they are not identical. Most of the metals are solids; few of them are liquids‚ such as mercury and cesium. Density of metals is not similar also. For example‚ sodium has density of 0.97g/cm3 while lead has density of 11.4g/cm3. Melting point of sodium is 98.0oC while for lead it is 327.6oC. Metals have the capability to lose electrons when they react with non-metals such as

Density of Metals Lab 1. Purpose The purpose of this lab was answered in 4 questions‚ and their answers are here shown. The density of the metals we used were 5g/cm3. The density of a metal piece does not depend on its size‚ it depends on the total mass and total volume. The most accurate way of determining density is dividing mass by volume. You can’t identify metals by their density. It can help you narrow the options down‚ but you can’t identify a metal by using only its density. 2. Question

Metal detectors in schools pose more of a threat than a sense of security. Every student carries metal of some form on them. Pens‚ pencils‚ notebooks and other school supplies all contain metals. If we try to make schools “safer” by placing metal detectors in the entrance and exit of every school building. With many school shootings and stabbings‚ media and parents have proposed new safety measures. Placing metal detectors and spending extra time on safety management takes time away from class and
