Problem based learning chemistry new elements activity

1. PROBLEM BASED
LEARNING
CHEMISTRY II

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.
