ionic bonding

• What does ionic bonding involve?

  Transfer of electrons between atoms
• Why do atoms do ionic bonding?

  To reach a full outer shell of electrons
• what does this transfer result in?

  the atoms becoming charged particles called ions
• What happens to ions with opposite charges?

  They attract so the ions bond together
• what does a ionic bond exist between

  a non metal and a metal
• What type of bond is formed when particles bond together through ionic bonds?

  Ionic bonds
• How are ions formed from atoms?

  Atoms lose or gain electrons
• What is the significance of the square brackets in ionic notation?

  They indicate the ion's charge
• What is the relationship between the charges of the ions in an ionic compound?

  They have opposite charges
• What type of forces attract the ions in an ionic compound?

  Electrostatic forces
• How strong is an ionic bond compared to a covalent bond?

  Similar in strength
• What is ionic bonding primarily involve?

  A metal atom transferring electrons to a non-metal
• What do oppositely charged ions form?

  An ionic bond through electrostatic attraction
• What do we call a compound formed by ionic bonding?

  An ionic compound
• How do ionic compounds typically exist in real life?

  They involve many ions in a lattice structure
• What is the arrangement of ions in an ionic compound?

  Positive and negative ions alternate in a lattice
• What are two key properties of ionic compounds?

  High melting/boiling points and electrical conductivity
• What determines the melting and boiling points of ionic compounds?

  The strength of the ionic bonds holding them together
• Why can ionic compounds conduct electricity when melted or dissolved?

  Charged particles are free to move
• What happens to ionic compounds in solid form regarding electricity?

  They cannot conduct electricity
• three properties that ionic compounds have:

  -High melting and boiling points, Conduct electricity when liquid, High strength bonds
• Why can ionic compounds only conduct electricity when in liquid/molten, or aqueous form?

  -The ions are free to move and carry charge
•  formulae for the following ions:

  1. Hydroxide:  OH-
  2. Sulphate:  SO42-
  3. Nitrate:  NO3-
  4. Carbonate:  CO32-
  5. Ammonium:  NH4+
