Topic 6

• The elements in Group 1 of the periodic table. They are typically soft and have relatively low melting points.

  Alkali Metals
• The ions formed by halogen atoms when they gain an electron. They have a 1- charge.

  Halides
• The elements in Group 7 of the periodic table. The halogens gain an electron to form halide ions with a 1- charge. Down the group the halogens gets less reactive and have higher melting and boiling points.

  Halogens
• Unreactive, like noble gases due to their stable electron configuration.

  Inert
• The elements in Group 0 of the periodic table. They have a stable full outer shell of electrons which makes them very unreactive.

  Noble Gases
• A reaction involving the gain of oxygen, the loss of electrons.

  Oxidation
• A reaction in which both oxidation and reaction occur simultaneously.
