Map of the Lesson on Chemical Bonding

According to the map above, which of the following are types of covalent bonds?
a) Polar.
b) Van der Waals.
c) Ionic.
d) Hydrogen.
e) None of the above.
Multiple Choice
How would you respond to this reasoning? Oxygen is not a greenhouse gas; therefore, gases containing oxygen—such as ozone, nitrous oxide, and carbon dioxide—are not greenhouse gases either.
Multiple Choice
The chemical characteristics or reactivity of an element depend mostly on the __________.
Multiple Choice
Some groups of chemical elements react similarly to one another. For example, the chemistries of sodium and of lithium are similar, as are the chemistries of chlorine and of iodine. These similarities in chemistry result when different elements have similar __________.
Multiple Choice
For most atoms, when does the configuration of electrons make the atom unreactive?
