2. Chemistry

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.

An atom that normally has __________ in its outer shell would not tend to form chemical bonds with other atoms.

The chemical characteristics or reactivity of an element depend mostly on the __________.

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 __________.

For most atoms, when does the configuration of electrons make the atom unreactive?

What are the defining characteristics of a condensation reaction? a. Two monomers are covalently bonded together and a water molecule is produced. b. Two monomers are covalently bonded together and a water molecule is used up. c. A polymer is broken down into monomers and a water molecule is produced. d. A polymer is broken down into monomers and a water molecule is used up.
