Transcript

  • 1. Chemistry PART 1
    • UNDERSTANDING
    • THE CONCEPT
    • OF
    • COVALENT BONDING
    www.sciencetutors.zoomshare.com
  • 2. QUICK QUIZZZZZ….
    • Only covalent compounds are called molecules.
    • TRUE or FALSE?
    www.sciencetutors.zoomshare.com
  • 3. BONDING IN MOLECULES Task What is bonding? What are Valence Electrons? Define the term Covalent. What is Covalent Bonding? www.sciencetutors.zoomshare.com
  • 4. What is Bonding
    • Bonding is the linking of atoms between a metal and non metal and or between two non-metals
    www.sciencetutors.zoomshare.com
  • 5.
    • What is Covalent Bonding?
    • A covalent bond is a strong bond between two non-metal atoms .
    www.sciencetutors.zoomshare.com
  • 6. Objective
    • To explain that a covalent bond arises from a shared pair of electrons
    www.sciencetutors.zoomshare.com
  • 7. Concept Of Valence Electrons
    • The electrons in the outermost shell are the valence electrons
    • These are electrons on an atom that can be gained or lost in a chemical reaction.
    www.sciencetutors.zoomshare.com
  • 8.  
  • 9. VALENCE ELECTRONS AND STABILITY
    • Many elements are stable when they contain eight electrons in their valence shell.
    www.sciencetutors.zoomshare.com Nitrogen Boron Carbon Chlorine Sodium Potassium Calcium Valence electron Electron Configuration Symbol Elements
  • 10. Calculating Valence Electrons Complete the table below: What are the symbols and valence Electrons of the following elements? Calcium Carbon Oxygen Potassium Chlorine Aluminium Magnesium Sodium
  • 11. OCTECTOF VALENCE ELECTRON
    • What is the symbol of Fluorine?
    • What is the atomic number of fluorine?
    • What is the electron configuration of fluorine?
    • Two fluorine atoms, for example, can form a stable F2 molecule in which each atom has an octet of valence electrons by sharing a pair of electrons.
  • 12. OCTECTOF VALENCE ELECTRON
    • What is the symbol of Fluorine?
    • What is the atomic number of fluorine?
    • What is the electron configuration of fluorine?
    • ANSWERS
    • Fluorine symbol (F)
    • Atomic number of fluorine is 9
    • Electron configuration is 2, 7
  • 13. QUICK QUIZZZZZZZ…
    • Explain how a pair of oxygen atoms can form an O2 molecule.
    • What is the total valence electron of each atom of oxygen in a covalent bond?
  • 14. Answers To Quick Quizzzzz…
    • Each atom of oxygen in a covalent bond has a total of eight valence electrons by sharing two pairs of electrons.
    www.sciencetutors.zoomshare.com
  • 15.
    • Covalent means sharing
    • Complete the table below using your Periodic Table. Write down examples of non-metals that can share electrons.
    Carbon Oxygen Hydrogen Chlorine Example of Non-Metal Example of Non-Metal
  • 16. Facts About Covalent Bonding
    • When non-metals react with non-metals they share electrons and form a covalent bond.
    • Single Covalent Bond
    • One pair of shared electrons
    www.sciencetutors.zoomshare.com
  • 17. Facts About Covalent Bonding
    • When non-metals react with non-metals they share electrons and form a covalent bond.
    • 2. Double Covalent Bond
    • Two pairs of shared electrons
    www.sciencetutors.zoomshare.com
  • 18. Facts About Covalent Bonding
    • When non-metals react with non-metals they share electrons and form a covalent bond.
    • 3. Triple Covalent Bond
    • Three pairs of shared electrons
    www.sciencetutors.zoomshare.com
  • 19.
    • What is Covalent Bonding?
    • A covalent bond is a form of chemical bonding that is characterized by the sharing of pairs of electrons between atoms, and other covalent bonds
  • 20. COVALENT BONDING
    • To introduce covalent bonding as the strong bonding between atoms in molecules
    • What is the Atomic Number Of Chlorine?
    • How many electrons are there in an atom of Chlorine?
    • What is the electron configuration of Chlorine?
    • How many more electrons does chlorine need to have a full outer shell?
  • 21. COVALENT BONDING
    • To introduce covalent bonding as the strong bonding between atoms in molecules
    • What is the Atomic Number Of Hydrogen?
    • How many electrons are there in an atom of Hydrogen?
    • What is the electron configuration of Hydrogen?
