reactions (metals and oxygen)

• If a metal forms an ion, will it have a positive or negative charge?

  positive
• If a non-metal forms an ion, will it have a positive or negative charge?

  negative
• Explain why atoms transfer electrons in ionic bonding.

  so the atoms can have a full outer shell
• Name the two different types of substances that form ionic bonds when they react together

  metals and non-metals
• State what is formed when a metal reacts with oxygen.

  a metal oxide
• Define oxidation in terms of the loss and gain of oxygen.


  Oxidation is the gain of oxygen.
• Define reduction in terms of the loss and gain of oxygen.


  Reduction is the loss of oxygen.
• If an atom gains electrons, state the type of charge it will have.

  Negative
• If an atom loses electrons, state the type of charge it will have.

  Positive
• An element is in Group 1. If it forms an ion, state what charge it will have.

  1+
• An element is in Group 2. If it forms an ion, state what charge it will have.

  2+
• An element is in Group 7. If it forms an ion, state what charge it will have.
