What is the vocabulary used to describe the naming of compounds?Â
Even though there are over 50 million substances in existence, some are so common that they are aptly given traditional names, which are referred to as the "common name." These include substances such as water (H2O) and ammonia (NH3).Â
What are the two categories of substances in order to name them?
"A" contain carbon and hydrogen, often in combination with oxygen, nitrogen, or other elements. All others are "B". Early chemists associated "C" compounds with plants and animals and "D" compounds with the nonliving portion of our world, for example minerals and water.Â
Metals bonding with nonmetals are classified as _________ compounds.
Some metals can form more than one type of ion. These metals are in the transitional metals of the periodic table. Since there are more than one variation of these elements bonding, they are differentiated using roman numerals.
Name the following ion: Na+
Name the following ion: Zn2+
Name the following ion: Al3+
Name the following ion: Fe2+
Name the following ion: Fe3+
Ions of the same element that have different charges have different phyical and chemical properties.
Which two transitional metals do not form more than one type of ion, and therefore will never use roman numerals?
Positively charged ions (cations) composed of purely nonmetals end in ______
Monatomic (mono-one, atomic-atom) anions (negatively charged ions), end in/with ______. Examples include H-, O2-, and N3-.
Polyatomic ions containing oxygen, are known as oxyanions. They end in one of two suffixes:Â
Name the following polyatomic ions:
