Organic Compound Notes
This educational guide delves into the basics of compounds, explaining what a compound is, the definition of an element, and the significance of element symbols. It covers essential concepts such as writing chemical formulas, identifying compound elements, and distinguishing between organic and inorganic compounds. The guide provides practice questions to enhance understanding, focusing on formulas like NaCl, H2O, and CO2, and categorizing compounds as organic or inorganic based on their carbon content.

Presentation Transcript
What is a compound? • A substance made of two or more elements chemically combined in a set ratio.
What is an element? • A substance that cannot be broken down into any other substances by chemical or physical means.
What is an element symbol? • One or two letter symbols identify most elements. • Example: H is for Hydrogen, O is for Oxygen, Ne for Neon
Writing chemical formula • The first letter of the chemical symbol will be a capital letter • Example: Carbon – C, Sulfur – S, Nitrogen – N • The second letter of the chemical symbol will be a lower case • Example: Calcium – Ca, Sodium – Na, Helium – He
Counting elements in the compound • Count the number of capital letters in the compound to identify how many elements are there in the compound. • Example: NaCl (salt) is made up of how many elements? • 2 elements (Na, Cl)
Let’s practiceHow many elements in the following compound? • C2 H3 N • C56 H58 Cl14 Cu N16 S4 • NaCl • H2O • CO2
Use Textbook 34-35 to identify the element of the following element symbol • B 9. Li • H 10. Ca • C 11. Na • O 12. Cu • P 13. Cl • N 14. Cr • S 15. Cs • Al
Compound Inorganic Organic
What is an organic compound? • All organic compounds contain the element carbon and may contain other elements such as hydrogen, oxygen, phosphorus, nitrogen and sulfur.
What is an inorganic compound? • All compounds that do NOTcontain the element carbon.
Identify as Organic or Inorganic Compound • C3H5NO • NaCl • CuO2 • CH3OH • C3H7NO2 • AlSb • BeCl2 • CdF2 • C7H5NOS • C6H5Br
