13 What type of bond is formed when electrons are shared? covalent
14 What type of bond forms from unequal sharing of electrons? Polar covalent
15 What is responsible for many of the properties of substances? their structure
16 What type of bond is found in individual molecules? covalent
17 What part of an atom is involved in chemical bonding? electron cloud
18 What property of the electrons in a metal gives the metal its properties? They move easily
19 Are covalent compounds good conductors of electricity when dissolved Are covalent compounds good conductors of electricity when dissolved? Why or Why not?No, molecules stay together and do not conduct an electrical current.
20 How do metal atoms bond together? Metal atoms share electrons with many other metal atoms at the same time.
21 Why do ionic compounds have high melting points? Each ion in a crystal is rigidly bonded to the several ions that surround it. Because each ion is strongly bonded to other ions, much energy has to be added to break the bonds.
22 What are three forms of the element carbon? Graphite, diamond, and fullerene
