Question
Chapter 2, Problem 7CT
Summary Introduction
To answer:
Neon (atomic mass 10) and argon (atomic mass 18) are inert elements, which mean that they very rarely form
Introduction:
Neon and argon are the inert elements that have completely filled valence electrons in their outer shells. The outermost valence electrons that did not attain complete electron configuration will only take part in the

a) Explain why some of the elements like TI and Pb on the lower left of the p block are metallic.
b) Explain why some of the elements like C, Si in the center of the p block form covalent bonds. Explain why these bonds formed
by the network of these elements (as studied in Chapter 25) tend to be unreactive.
c) Explain why the noble Group 8A elements are highly unreactive gases.
d) Explain why some elements like F, CI, Br etc, on the upper right of the p block are highly reactive nonmetals.
Chlorine is an element with the symbol Cl. Draw and label atomic structure of chlorine indicating the number and locations of protons, neutrons and electrons in one atom of chlorine.
Unshared, or lone, electron pairs play an important role in determining the chemical and physical properties of organic
compounds. Thus, it is important to know which atoms carry unshared pairs.
Use the structural formulas below to determine the number of unshared pairs at each designated atom.
Be sure your answers are consistent with the formal charges on the formulas.
