PPT-N4/5 Chemistry Metals Properties of Metals

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. This instability is what drives the process of corrosion and it results from the fact that a refined metal is continually trying to revert to its natural state the mineral Some metals do this faster than others The Galvanic Series ranks corrosion te Actinides. The first . actinide that was . discovered . was . Uranium by Klaproth in 1789 . Element numbers 89-103 make up the group of actinides. Known as Rare earth metals. On the periodic table they are located under the . 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. . METAL CHEMISTRY. N4. CHEMISTRY. N5. CHEMISTRY. After completing this topic you should be able to : . OBTAINING METALS. State ores are naturally occurring compounds of . metals.. State . the less reactive metals, including gold, silver and copper, are found uncombined in the Earth’s crust and the more reactive metals have to be extracted from their ores. 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. 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. 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 Well… What is chemistry?. First, we need to think about what science is.. Right now as you sit in my class, your tummy is making a weird sound.. What is that sound?. Why is it happening?. What can you do to stop the sound?. 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.
