UNIT 3 LEARNING TARGETS

Chapter 6

Vocabulary:

metals nonmetals metalloids (semimetals) alkali metals alkaline earth metals

halogens noble gases (inert gases) representative elements group period

transition metal inner transition metal atomic radius ion ionization energy

ionic radius cation anion electronegativity shielding nuclear charge

1. Periodic Table Structure

   1. Be able to explain how the elements are organized on a periodic table

   2. Be able to locate the alkali metal, alkaline earth metal, transition metals, boron family, carbon family, nitrogen family, oxygen family, halogen, and noble gas families on a periodic table.

   3. Be able to identify groups vs. periods on the periodic table.

   4. Distinguish between representative elements (group A: 1, 2, 13-18) and transition elements/metals (group B: 3-12).

   5. Distinguish between s, p, d and f blocks on the periodic table

2. Periodic Trends

   1. Identify and characterize three broad classes of elements: metals, nonmetals, metalloids (semimetals).

   2. Describe periodic trends for atomic/ionic radius (size), ionization energy, and electronegativity.

   3. Be able to describe/explain the underlying cause for each periodic trend (atomic size, nuclear charge, shielding, etc)

   4. Be able to compare elements based on periodic trends

3. Ions

   1. Explain how ions form

   2. Identify the type(charge) of ion formed based on valence electrons
