Constructed Response . Topic 2: The Periodic Table
Set C: Lewis electron-dot diagram, electronegativity, periodic trend
Base your answers questions 7 and 8 on the information below.
Fluorine is a Group 17 element. Fluorine is the most electronegative and reactive of
all elements. It is a pale yellow, corrosive gas, which reacts with practically all
organic and inorganic substances.

9. Explain why the electronegativity of elements in Group 17 9.
decreases from top to bottom down the group.
Set D: Ionization energy, trend, properties of groups
A knowledge of the ionization energies of elements can be very useful in
predicting the activity and type of reaction an element will have.
