Chapter 8, Problem 8.79QP

Interpretation Introduction

Interpretation:

Match each of the given elements on the right with its description on the left.

Concept introduction:

Metals are elements that usually contain 1-3 outer shell electrons. Metals look shining and lustrous and are malleable and ductile. They are also good conductors of heat and electricity. They have low ionization energy and tend to lose electrons forming cations. They are most likely to form ionic compounds.

Nonmetals are elements that usually contain 4-8 outer shell electrons. They cannot conduct heat and electricity and are brittle. Also they have high electron affinities and tend to gain electrons forming anions. They are most likely to form molecular compounds.

Elements with same valence electrons are placed in the same group in periodic table

Noble gases are inert gases with completely filled electronic configuration. Helium, neon, argon, xenon, krypton, and radon are the noble gases.
