Elements and Compounds Lesson 2: Transcript
Elements v Compounds Element Oxygen Compound Carbon Dioxide The Letters of Life Just like words are made up of letters compounds are made up of elements Water Baking Soda Capsaicin. Chapter 4.10,4.11 and 5. Combining Elements. When we begin combining elements we make compounds.. Two types. Non-metal and metal. Non-metal and non-metal. Each type has unique physical and chemical properties. September . 17, . 2012. . Ms. Smith. Mrs. Malone. DO NOW:. Date. : . September 17, 2012. TEKS 6.5B Recognize that . a limited number of the many known elements comprise. the largest portion of solid . Part . 1: Decomposition and Synthesis Reactions. . Objectives. -To identify decomposition and synthesis chemical reactions. -To predict the products of these two types of reactions. 2. Symbols in . Mix and Match. Write the electron configuration for Chlorine (. Cl. ) and Magnesium (Mg) and then for their ions.. Draw a diagram of the structure of an atom.. Fill in the table:. Revision. Particle. 1. st. Year Chemistry. 1. Elements. Elements & Atoms. All substances are made up from tiny particles called atoms. When a substance is made up of only one type of atom it is called an element. The element iron is made up of iron atoms, the element hydrogen is made up of hydrogen atoms, the element sulphur is made up of sulphur atoms and so on.. Another way of classifying chemical compounds… . Organic Compounds. In science, organic compounds contain . carbon. (. C. ), and usually . hydrogen. (. H. ). Sometimes other types of atoms are also attached, including: . Pure Substances. A sample of matter that has definite chemical and physical properties.. Elements. Atoms. Compounds. Molecules. Elements. pure substance that cannot be separated into simpler substance by physical or chemical means. . Chapter 5: Molecules and Compounds. Learning Goals. Write . chemical formulas.. Determine . the total number of each type of atom in a chemical formula.. Classify . elements as atomic or molecular.. Classify . 2. . How many different types of atoms is helium made up of?. 3. Draw the Bohr model for helium (there are two neutrons in helium).. Today’s Objectives. SWBAT explain that a ‘chemical formula’ describes the combination of two or more elements.. Dr. . Nouf. H. Alotaibi. P-block Elements- V A elements. General trend. Electron configurations ns. 2. np. 3. (n is the period number). The s orbital is completely filled and p orbital is half filled which makes them stable.. . (. b) Compounds. Specific . Aim : To appreciate the idea pure substances, to know about Elements and . Compounds to . be able to identify both Elements and compounds present around us, to know . Dr. . Nouf. H. . Alotaibi. Group 17 elements, fluorine (F), chlorine (Cl), bromine (Br), iodine (I) and astatine (At), belong to halogen family. . Electron configurations ns. 2. np. 5. (n is the period number).. Edward C. Gregor. Managing Director. Edward C. Gregor & Associates, LLC. New & Emerging Technology. 3rd Largest Volume Thermoplastic Globally. Cross-Head Extruded Yarns. (Roller Shades). Coated Fabrics (Billboards, Banners, Tents, etc.). Alkaloids and Heterocyclic Compounds.. . Alkaloids. Alkaloids are a class of basic and cyclic organic compounds, naturally occurring consist of carbon, hydrogen mainly, and nitrogen and usually oxygen. .
