Practice: The strength of an ionic bond comes principally from:
a) The converting of atoms into compounds.
b) The movement of electrons from cations to anions.
c) The mutual attraction of opposite electrical charges.
d) The sharing of electrons.
A chemical bond is the connection of different elements through the sharing, transferring or pooling of electrons.
Concept #1: Chemical Bonds
Concept #2: Ionic Bonding
Ionic bond occurs through a transfer of an electron from a metal to a non-metal in order to create opposing charges.
Example #1: Which of the following species has bonds with the most ionic character?
Practice: The strength of an ionic bond comes principally from:
a) The converting of atoms into compounds.
b) The movement of electrons from cations to anions.
c) The mutual attraction of opposite electrical charges.
d) The sharing of electrons.
Concept #3: Covalent Bonding
Covalent bond involves sharing of the valence electrons between two non-metals, giving both a filled outer shell like a noble gas closest to them.
Example #2: Which of these elements is unlikely to form covalent bonds?
Concept #4: Metallic Bonding
Metallic bond occurs through attractive force between free flowing valence electrons and positively charged ions on metal's surface.
Example #3: Which of the following is best description of the free flowing electrons in metallic bonding?
Practice: Which of the following is not a physical property attributed to metallic bonding?
a) Ductility
b) Luster
c) Brittleness
d) Malleability
e) Conductivity
Practice: Which of the following statements is true?
a) O2 is characterized by metallic bonding.
b) BaO is characterized by covalent bonding.
c) H2O is characterized by ionic bonding.
d) Zn is characterized by metallic bonding.
