Presentation Transcript

  1. Do Now • Compared to a calcium atom, the calcium ion Ca2+ has • more protons • fewer protons • more electrons • fewer electrons • What is the correct Lewis electron-dot structure for the compound magnesium fluoride?

  2. Covalent Bonding Williamsburg High School for Architecture and Design Mr. Quinn and Ms. Tom 11/18/13

  3. Aim • How do atoms share electrons?

  4. From last week… • Ionic bonds are a metal and a nonmetal • They make compounds called salts

  5. New Information group of non-metals that bonds by sharing electrons and has no charge • Same or different atoms • Covalent bonds • Low melting/boiling point Molecule

  6. Lewis Structures IV: A New Type

  7. A&D vs. Regents, Round 1 • Covalent bonds are formed when electrons are • transferred from one atom to another • captured by the nucleus • mobile within a metal • shared between two atoms

  8. A&D vs. Regents, Round 2 • As a bond between a hydrogen atom and a sulfur atom is formed, electrons are • shared to form an ionic bond • shared to form a covalent bond • transferred to form an ionic bond • transferred to form a covalent bond

  9. A&D vs. Regents, Round 3 • Which type of bonding is found in all molecular substances? • covalent bonding • hydrogen bonding • ionic bonding • metallic bonding

  10. A&D vs. Regents, Round 4 • A molecular compound is formed when a chemical reaction occurs between atoms of • chlorine and sodium • chlorine and yttrium • oxygen and hydrogen • oxygen and magnesium

  11. A&D vs. Regents, Round 5 • In which compound do atoms form bonds by sharing electrons? • H2O • Na2O • CaO • MgO
