Ionic bonding

• What is the main objective of the lesson on ionic bonding?

  To describe how ions are formed from atoms
• What types of substances form ionic bonds?

  Metals and non-metals
• Why do chemical reactions occur?

  To achieve a full outer shell of electrons
• What happens to products after a chemical reaction?

  They are unlikely to react again
• What are the two types of chemical bonds?

  • Ionic bonds
  • Covalent bonds
• How are ionic bonds formed?

  Electrons are transferred from one atom to another
• Who typically forms ionic bonds?

  Metals and non-metals
• What is the strength of ionic bonds compared to covalent bonds?

  Ionic bonds are generally strong
• What is the state of ionic compounds at room temperature?

  Usually solid
• What are the melting and boiling points of ionic compounds?

  They have high melting and boiling points
• Can ionic compounds conduct electricity?

  Yes, they can conduct electricity
• How do metals achieve a full outer shell?

  By losing their outer shell of electrons
• How do non-metals achieve a full outer shell?

  By gaining electrons to fill their outer shell
• What are ions?

  Charged atoms
• How are ions formed?

  When an atom gains or loses electrons
• What does Li+ represent?

  Lithium has lost one electron
• What does O2- represent?

  Oxygen has gained two electrons
• What are cations and anions?

  Cations are positive ions; anions are negative ions
• What is the structure of ionic substances?

  • Made up of alternating ions
  • Form a lattice (3D network)
• Why do atoms react in terms of stability?

  Atoms want to gain a full outer shell for stability
• How do metals and non-metals achieve stability?

  Metals lose electrons; non-metals gain electrons
