The student will know:
1. Vocabulary: Dmitri Mendeleev, Henry Mosely, atomic mass, atomic number, valence electrons, alkali metals, alkaline earth metals, transition metals, halogens, noble gases, atomic radius, ionization energy, electronegativity, s block, p block, d block, f block, period and group
2. Know how to identify how many valence electrons an atom has given an electron configuration for that element.
3. Know how to rank elements according to atomic radius, ionization energy and electronegativity based on the periodic radius trends across a period and down a group on the periodic table.
