T’Keyah Driskell. &. Lyric Williams. I. ntroduction. In our PowerPoint Presentation, we will be explaining what alkaline earth metals are and some of their uses, reactions, properties, etc. . We will tell what the four metals in the group are, and their mass, density, and melting point are. . 30. th. April 2012. 1. Dubai continues to play an important role in the Gold trade. The Gold business, has witnessed very strong growth in Dubai over the past decade. World supply of gold in 2011 was ~ 4000 . Beta Science . Mr. McMartin. Vocabulary. Element: a substance that cannot be separated or broken down into simpler substances by chemical or physical means.. Pure Substance: a sample of matter, either a single element or a single compound, that has definite chemical and physical properties.. Mechanical. Industrial Materials . UOG. By: Jahangir . Rana. Metals. All . metals belong to one of these two groups. .. Ferrous Metals. Non-Ferrous Metals. Ferrous metals. Ferrous metals are metals, which are mainly made of iron with small amounts of other metals or elements added in order to give the correct properties. Almost all ferrous metals are magnetic and can be picked up with a magnet. These metals rust or oxidise if not treated as they contain iron.. What makes up matter?. By Amelia. Atoms. : an atom is the smallest particle of an element. Atomic number. : the number of protons in a nucleus is the elements atomic number. Each element is made of one kind of atom, so elements are called pure substances . Junior Science. 1. Recognising . chemical and physical change. Physical changes . are . reversible and does . not produce a new substance. Changes in state . (. melting, freezing, vaporization, condensation, sublimation. Design and Manufacture. . Alloys. Typical Alloys. Brass ( Copper & Zinc). Steel (Iron & Carbon). Cast Iron (Iron & Carbon). Duralium. (Aluminium & Copper). Bronze (Copper, Tin, Phosphorus). Describe the difference between the structures of diamond and graphite.. Explain the different properties of these versions of carbon.. Graphite. Diamond. Learning questions. What general properties do metals have?. The elements in group 1, on the left of the periodic table, are called the. . alkali metals. .. These metals are all very . reactive which makes them different from other metals. lithium. sodium. potassium. Patel Sikora. What are Alkali Metals?. The alkali metals are located in Group 1 of the periodic table. They are a series of chemical elements which have similar trends and properties. Alkali metals are so called because when they react with water alkalis (strong bases that can neutralize acids) are formed.. Properties of Metals. Worksheet .  Metals. ¾ of all known elements. Solid at room temp (NOT Mercury). Low IE = give up electrons. Metallic bonds. Delocalization. Malleable, ductile. Alkali Metals. Unit 2 Review: Chemistry Matter that has Chemical and Physical Properties Key Concepts • Particle theory of matter • States of matter • Classifying matter • Observing physical properties • Observing chemical properties MATERIAL SCIENCE & METALLURGY. What is material science? What is metallurgy? Why this subject is studied? . Brief classification of engineering materials. Important properties of each category of engineering materials. Strength. – metals that are . strong. are used to make car bodies, bike frames, ships, planes etc. . Malleability. . (mouldable). – This means that that they can be . shaped by hammering or rolling.
