Forming ionic bonds

• What is an ionic compound made up of?

  Charged particles called ions
• What type of structure does an ionic compound have?

  A giant lattice structure
• What are the forces of attraction in an ionic compound?

  Strong electrostatic forces of attraction
• What forms positive and negative ions?

  When a metal reacts with a non-metal
• How do metals and non-metals form ionic bonds?

  By transferring electrons
• What is an electron?

  A subatomic particle with a negative charge
• What is ionic bonding?

  It forms between two atoms when an electron is transferred from one atom to another
• What do dot and cross diagrams represent in ionic bonding?

  The transfer of electrons from metal atoms to non-metal atoms
• How are electrons represented in dot and cross diagrams?

  Electrons from one atom are shown as dots and from the other as crosses
• What happens when sodium reacts with chlorine in terms of electron transfer?

  Electrons transfer from sodium atoms to chlorine atoms
• What is the process of ionic bonding in magnesium chloride?

  • Magnesium transfers electrons to chlorine atoms
  • Forms positive magnesium ions and negative chloride ions
  • Creates an ionic bond through electrostatic attraction
• What are the properties of ionic compounds?

  • High melting and boiling points
  • Conduct electricity when dissolved in water
  • Form crystalline structures
• What is the role of the outer electron in sodium during ionic bonding?

  The outer electron transfers to the outer shell of a chlorine atom
• What is the ionic bond formed between?

  Between oppositely charged ions
• What does the term 'ionic lattice' refer to?

  The regular arrangement of ions in an ionic compound
• How does the ionic bonding process differ between sodium chloride and magnesium oxide?

  Different metals transfer different numbers of electrons
• What is the visual representation used to model ionic bonding?

  Dot and cross diagrams
• What do the images in the slideshow represent regarding ionic bonding?

  Dot and cross diagrams for ions in sodium chloride, magnesium oxide, and calcium chloride
• What is the purpose of the question about drawing a diagram for magnesium chloride?

  To show how the electrons are transferred when magnesium chloride is formed
• What is the significance of the outer electrons in ionic bonding?

  They are involved in the transfer that forms ions
• How does the ionic bond strength relate to the properties of ionic compounds?

  Stronger ionic bonds lead to higher melting and boiling points
