Problem based learning chemistry new elements activity
- 2. Objective and Expected Learning: • Present 5 new compounds to the IUPAC (International Union of Pure and Applied Chemistry) • Role: Chemist on the committee for nomenclature and symbols. • Audience: Members of the IUPAC • Situation: You are a member of a team of chemists with the responsibility of presenting 5 new compounds to the IUPAC. As part of this presentation, you must describe the physical properties of each element and the final compound. • The rules by which you have named these new compounds. • You must present a “sample” of this compound to the assembly

- 9. Rules to Name the New Compounds: 1. When combining elements of the first and second periods of the new periodic table, all first elements should be named with their respective charges using Mayan Numerals. 2. The charge of any given element is determined by which period they are on. 3. The heavier elements are named after the lighter one, however, they are represented first on the periodic table. 4. The element’s indicated charge on the formula corresponds to its charge, and not the element that is combining with.
