Key Concepts
Here are the essential concepts you must grasp in order to answer the question correctly.
Ionic Compounds
Ionic compounds are formed from the electrostatic attraction between cations (positively charged ions) and anions (negatively charged ions). They typically consist of a metal and a non-metal, where the metal donates electrons to become a cation, while the non-metal accepts electrons to become an anion. Understanding the formation and naming conventions of these compounds is essential for completing the table.

Ionic Compounds Naming
Nomenclature of Ions
The nomenclature of ions involves specific rules for naming cations and anions. Cations are usually named after their parent element, often with the addition of a Roman numeral to indicate their charge, while anions typically have names derived from their parent element with suffixes like '-ide', '-ate', or '-ite' depending on their composition. Familiarity with these naming conventions is crucial for accurately filling in the table.

Chemical Formulas
Chemical formulas represent the composition of ionic compounds, indicating the types and ratios of ions present. The formula is derived from the charges of the cations and anions, ensuring that the overall charge of the compound is neutral. Understanding how to derive and interpret these formulas is key to completing the first column of the table correctly.

Textbook Question
The first atoms of seaborgium (Sg) were identified in 1974. The longest-lived isotope of Sg has a mass number of 266. (b) Atoms of Sg are very unstable, and it is therefore difficult to study this element's properties. Based on the position of Sg in the periodic table, what element should it most closely resemble in its chemical properties?

Textbook Question
Cyclopropane is an interesting hydrocarbon. Instead of having three carbons in a row, the three carbons form a ring, as shown in this perspective drawing (see Figure 2.18 for a prior example of this kind of drawing):
Cyclopropane was at one time used as an anesthetic, but its use was discontinued, in part because it is highly flammable. (b) The three carbon atoms are necessarily in a plane. What do the different wedges mean?
