Ionic Bonding&Properties of Ionic Compounds

• What is the main topic of the video?

  The formation and properties of ionic compounds.
• What are the key properties of ionic compounds?

  • Form giant ionic lattices
  • High melting and boiling points
  • Cannot conduct electricity when solid
  • Can conduct electricity when molten or dissolved in water
• What is ionic bonding?

  Ionic bonding occurs when a metal reacts with a non-metal, transferring electrons to form ions.
• What happens to sodium and chlorine during their reaction?

  One electron is transferred from sodium to chlorine, forming sodium ions and chloride ions.
• What charge does a sodium ion have?

  A sodium ion has a one positive charge.
• What charge does a chloride ion have?

  A chloride ion has a one negative charge.
• Why do sodium and chloride ions have a full outer energy level?

  They achieve a stable electronic structure similar to that of a group zero noble gas.
• What is the name of the compound formed from sodium and chlorine?

  Sodium chloride.
• What is a giant ionic lattice?

  • A three-dimensional structure
  • Positive ions surrounded by negative ions
  • Negative ions surrounded by positive ions
• What are the forces of attraction in a giant ionic lattice called?

  Electrostatic forces of attraction.
• What do we call the forces that hold positive and negative ions in place?

  These forces are called ionic bonds.
• Why do ionic compounds have high melting and boiling points?

  • Strong electrostatic forces of attraction
  • Require a great deal of heat energy to break
• What is the main focus of the video on ionic bonding?

  Describing electron transfer during ionic bonding between group two metals and group six non-metals
• What is the melting point of sodium chloride?

  Around 800°C.
• Why can't ionic compounds conduct electricity when solid?

  In solid form, ions are locked in place and cannot move to carry charge.
• What is ionic bonding?

  • Transfer of electrons from metals to non-metals
  • Formation of positive and negative ions
  • Achieving stable electronic structure of noble gases
• How can ionic compounds conduct electricity when molten or dissolved in water?

  The ions can move freely and carry electrical charge.
• Which groups of elements are involved in ionic bonding as discussed in the video?

  Group two metals and group six non-metals
• What is the key point to remember about how ionic compounds conduct electricity?

  It is the ions that move, not electrons.
• What happens to the outer electron of a lithium atom during ionic bonding with fluorine?

  The outer electron moves to the fluorine atom
• What type of ion does lithium form after losing its outer electron?

  One positive lithium ion
• What type of ion does fluorine form after gaining an electron?

  One negative fluoride ion
• What should you be able to describe by the end of the video?

  How electrons are transferred during ionic bonding and how to draw Dot and cross diagrams for ionic bonding.
• What is the significance of a full outer energy level in noble gases?

  • It is stable
  • Noble gases are unreactive
• What is the maximum number of electrons that can be held in the first energy level?

  Two electrons.
• How many electrons can the second and third energy levels hold?

  Eight electrons each.
• Why do elements react?

  To achieve a full outer energy level for stability.
• Where are metals and non-metals located on the periodic table?

  • Metals are on the left-hand side
  • Non-metals are on the right-hand side
• What type of bonding occurs when a metal reacts with a non-metal?

  Ionic bonding.
• What is the group number of lithium?

  Group one.
• What is the group number of fluorine?

  Group seven.
• How many electrons does a lithium atom have?

  Three electrons.
• How many electrons does a fluorine atom have?

  Nine electrons.
• What happens to the outer electron of a lithium atom during ionic bonding?

  It is lost to form a lithium ion.
• What happens to the outer electrons of a fluorine atom during ionic bonding?

  It gains an electron to form a fluoride ion.
• What is an ion?

  • An atom with an overall charge
  • Formed when an atom loses or gains electrons
• What charge does a lithium ion have?

  One positive charge.
• What charge does a fluoride ion have?

  One negative charge.
• What do both lithium and fluoride ions achieve after ionic bonding?

  • A full outer energy level
  • A stable electronic structure of a noble gas
• What is a typical exam question regarding ionic bonding?

  Describe the reaction between a group one metal and a group seven non-metal.
