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 3 rd 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
