Ionic bonding

• What are the three types of bonding that need to be known?

  Ionic, covalent, and metallic
• What happens when a metal and a non-metal react together in ionic bonding?


  The metal atom loses electrons
• What is ionic bonding characterized by?


  • Transfer of electrons
  • Involves a metal and a non-metal
  • Results in the formation of charged ions
• What is ionic bonding primarily characterized by?


  Transfer of electrons
• What type of charges do ionic compounds have?


  Opposite charges
• What causes the attraction in ionic bonding?


  Electrostatic forces
• How strong is an ionic bond?


  Very strong
• What is the electron configuration of sodium (Na)?


  2,8
• What is the electron configuration of chloride (Cl)?


  2,8,8
• What does a dot and cross diagram represent?

  The distribution of electrons in ionic bonding
• What is the charge of a magnesium ion (Mg)?


  2+
• What is the nature of ionic bonding?


  Electrostatic attraction between oppositely charged ions
• Between which types of ions does ionic bonding occur?


  Positive metal ions and negative non-metal ions
• What is the dot and cross diagram for the formation of Magnesium chloride (MgCl₂)?


  • Involves 3 atoms: 1 Magnesium and 2 Chlorides
  • Shows transfer of electrons from Magnesium to Chloride
  • Represents ionic bonding through electrostatic attraction
• What is the chemical formula for Magnesium chloride?


  MgCl₂
• How does the electron transfer in ionic bonding affect the stability of the resulting compound?


  It leads to the formation of stable ionic compounds due to full outer electron shells
