  1. The Boron Family(Group 13)

  2. Boron • Produces a green flame • Shiny and black in appearance • Melting point: 2300 Celsius • Boiling point: 2550 Celsius • Boron occurs sparsely throughout the world

  3. Aluminum • Soft texture • Lightweight and silver color • Melting Point: 660.5 Celsius • Boiling Point: 2467 Celsius • 3rd most abundant element in the Earth’s crust

  4. Gallium • Soft as lead • Silver in color • Melting Point: 29.8 Celsius • Boiling Point: 2403 Celsius • Can stimulate metabolism

  5. Indium • Rare metal • Abundance similar to silver • Melting Point: 156.2 Celsius • Boiling Point: 2080 Celsius • Can also stimulate metabolism

  6. Thallium • Resembles lead • Melting Point: 303.6 Celsius • Boiling Point: 1457 Celsius • Very toxic

  7. Chemical • All the elements have an oxidation state of +3 or +1 • All elements in the Boron group except Boron itself are soft in texture • They all have 3 electrons in valence shells • They are reactive at moderate temperatures except Boron which is reactive at higher temperatures • The Boron family has both metals and non-metals

  8. Chemical Reactions • All elements is Group 13 react to oxygen • The oxides of the metals in Group 13 are basic • The oxides of the nonmetals in Group 13 are acidic • Boron and Thallium react with halogens such as fluorine, chlorine, and bromine • Aluminum reacts with the halogens chlorine, iodine, and bromine • Gallium and Indium are not highly reactive with halogens
