Explain why noble gases don't have electronegativity values.
Electronegativity is ability to attract electrons in a bond. Noble gases are stable with a full valence shell, therefore do not bond or attract electrons.

In comparing the effective nuclear charge of Cl- to F-, which one would be higher? When becoming an anion, would the atomic radius increase or decrease?
F-; increase
400
Based on the following Ionization Energies, identify the atom with the largest atomic radius.
A - 494

Explain the difference in ionization between Mg and Al on the periodic table.
Mg - 738.1 kJ/mol
Al - 577.9 kJ/mol
Mg is higher because it is harder to take away its the electron from a stable s orbital.

Identify the charges of the following elements:
K S Br Al
K+ S2- Br- Al3+
