### Quiz: Chemical Formulas**Question 1:** What is the formula for **copper(I) oxide**? [Insert Answer Here]**Question 2:** What is the formula for **silver chloride**? [Insert Answer Here]**Question 3:** What is the formula for **iron(III) bromide**? [Insert Answer Here]This exercise challenges students to apply their knowledge of chemical nomenclature and oxidation states to determine the correct formulas for given compounds. To solve these, students should recall the valency of each element as indicated by its oxidation number and assemble the correct chemical formula accordingly. For example, copper(I) indicates a +1 oxidation state for copper. **Question:**What is the formula of the ionic compound expected to form between the elements I and Al?**Answer:**The compound expected to form is AlI₃.**Explanation:**When aluminum (Al) and iodine (I) react to form an ionic compound, they combine in a ratio that balances their charges. Aluminum commonly forms a +3 ion (Al³⁺) and iodine forms a -1 ion (I⁻). To balance the charges, three iodine ions are needed for every aluminum ion, resulting in the formula AlI₃.

In ionic compound the total positive charge of the cation is equal to the total charge of the anion.

Fill in the blank with the correct response: Recall the rules for naming cations, anions, and ionic compounds.Cations are named according to the following rules. • When a cation is made from a metal atom, it is given the same name as the metal. For example, K+ is called the potassium ion, and Mg2+ is called the magnesium ion. • Certain metals, particularly transition metals, can form multiple cations, each with a different charge. In that case, the name of the metal is followed by a (______________) letter or number or Roman numeral (enclosed in parentheses) that indicates the amount of charge. For example, tin can form the cations Sn2+ and Sn4+. Sn2+ is called the tin(II) ion and Sn4+ is called the tin(IV) ion. Mercury is unique in that it can form the cations Hg22+ and Hg2+. Hg22+ is called the mercury(I) ion and Hg2+ is called the mercury(II) ion. • Some polyatomic cations are formed from nonmetal atoms, and they are named with the suffix -ium.…

Read: On page three, paragraph one reads, "As the prefix, poly means many and atomic is related to atoms. An ion with more than one atom is a polyatomic ion. This differentiates polyatomic ions from monoatomic ions, which contain only one atom." A polyatomic ion is a group of covalently bonded atoms, with the total number of protons not equal to the total number of electrons. Atoms become ions when they gain or lose electrons, resulting in a net charge. On page one paragraph two it says. "The Octet rule describes the tendency of atoms to prefer valence shells with eight electrons. Atoms react and tend to create more stable compounds since they have fewer electrons. When discussing the octet rule, d or f electrons are not considered." According to the octet rule, atoms typically have eight electrons in their valence shell. Elements in the S block and P-block follow the Octet rule. On page two, paragraph one, "To draw a Lewis Structure, start with the atomic symbol in the middle, then…
