PPT-RED 1. What are the properties/characteristics of metals?

2 What are the propertiescharacteristics of nonmetals 3 What are the propertiescharacteristics of metalloids 4 What is a pure substance Is compound or an element 5 What is a mixture. 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 . Why are metals used to make these items?. Properties of metals . What property of metals is being . utalised. in the images on the previous slide?. Fishing sinker. Cooking pot. Electrical wires. Bread ties. Scientists classify elements into groups based on their properties. . A . physical property. is a characteristic of a substance that can be observed without changing the substance into another substance. Color, hardness, and shine (or . 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?. Sun. Moon. Mars. Venus. Saturn. Jupiter. Mercury. Symbols used in the 16. th. and 17. th. Century. Gold. Silver. Iron. Copper. Lead. Tin. Mercury. Alchemical Symbols used in the 15. th. Century. Fire. 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. EQ. : Just WHERE are these elements with . similar . properties?. Wake Up!. Sing along (if you’d like!). Song: Day 3 with the words. Song: Day 2 with pictures. Song: Day 1 on the periodic table. 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 Elements are pure substances made up of atoms that cannot be broken down. . These Elements are categorized by characteristics as: . Metals. Semi Metals or Metalloids . Non-Metals – Gases . What are atoms? . 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.
