The elements in groups 13, 14, and 15 of the periodic table include a mixture of metals, metalloids, and nonmetals.
### Group 13 (IIIA)
- **Elements**: Boron (B), Aluminum (Al), Gallium (Ga), Indium (In), Thallium (Tl), and Nihonium (Nh).
- **Characteristics**: This group includes metals (like aluminum and gallium), a metalloid (boron), and less commonly known elements. Group 13 elements generally form +3 oxidation states.
### Group 14 (IV A)
- **Elements**: Carbon (C), Silicon (Si), Germanium (Ge), Tin (Sn), Lead (Pb), and Flerovium (Fl).
- **Characteristics**: This group contains nonmetals (like carbon), metalloids (like silicon and germanium), and metals (like tin and lead). Elements in this group can exhibit oxidation states of +4, +2, or -4 (in the case of carbon).
### Group 15 (V A)
- **Elements**: Nitrogen (N), Phosphorus (P), Arsenic (As), Antimony (Sb), Bismuth (Bi), and Moscovium (Mc).
- **Characteristics**: This group includes nonmetals (like nitrogen and phosphorus), metalloids (like arsenic), and metals (like bismuth). Elements here typically exhibit oxidation states of -3, +3, and +5.
### Summary
- **Group 13**: Metals (Al, Ga, In, Tl), Metalloid (B), and a synthetic element (Nh).
- **Group 14**: Nonmetals (C), Metalloids (Si, Ge), and Metals (Sn, Pb), with a synthetic element (Fl).
- **Group 15**: Nonmetals (N, P), Metalloids (As), and Metals (Sb, Bi), with a synthetic element (Mc).
In general, while groups 13, 14, and 15 include both metals and nonmetals, they also incorporate metalloids that display properties of both categories. The reactivity of these elements varies widely, with some being very reactive (like nitrogen and phosphorus) while others, especially heavier metals, are less reactive.
