Question

question 1. a student is learning how to name binary ionic compounds. the student knows that these compounds consist of a metal and a nonmetal. some metals can form more than one type of ion, while others can only form one type. the student has the following information about the rules for naming binary ionic compounds: - the metal is always named first, followed by the nonmetal. - if the metal can form more than one type of ion, the charge on the metal ion must be indicated in the name. - the nonmetal is named by taking the root of its element name and adding the suffix \-ide.\ - for metals that form only one type of ion, the charge is not included in the name. which of the following statements are correct regarding the naming of binary ionic compounds? the nonmetal is named first, followed by the metal. if the metal can form more than one type of ion, the charge is indicated in the name using roman numerals. the nonmetal is named by taking the root of its element name and adding the suffix \-ide.\ if the metal can form only one type of ion, the charge is indicated in the name using roman numerals. the name of the metal is always placed second in the compound’s name.

Explanation:

1. Analyze each statement:

• "The nonmetal is named first, followed by the metal." → Incorrect. The rule states the metal is named first.
• "If the metal can form more than one type of ion, the charge is indicated in the name using Roman numerals." → Correct. The given rules say the charge must be indicated for such metals, and Roman numerals are the standard way.
• "The nonmetal is named by taking the root of its element name and adding the suffix '-ide'." → Correct. This matches the provided rule.
• "If the metal can form only one type of ion, the charge is indicated in the name using Roman numerals." → Incorrect. The rule says the charge is not included for metals with only one ion type.
• "The name of the metal is always placed second in the compound’s name." → Incorrect. The metal is named first.

Answer:

• If the metal can form more than one type of ion, the charge is indicated in the name using Roman numerals.
• The nonmetal is named by taking the root of its element name and adding the suffix "-ide."
