What is the name of the ionic compound CaCO3? Enter the name in all lowercase letters (including any roman numberals) with no spaces after the names.
What is the name of the ionic compound AgBr? Enter the name in all lowercase letters (including any roman numberals) with no spaces after the names.
The Correct Answer and Explanation is :
The ionic compound CaCO₃ is named “calcium carbonate.”his compound consists of calcium ions (Ca²⁺) and carbonate ions (CO₃²⁻).alcium, a Group 2 metal, forms a cation with a +2 charge, while the carbonate ion is a polyatomic ion with a -2 charge.he charges balance each other, resulting in a neutral compound.
he ionic compound AgBr is named “silver bromide.”ilver (Ag) typically forms a +1 cation, and bromine (Br) forms a -1 anion.he charges are equal and opposite, leading to a neutral compound.
n naming ionic compounds, the cation is named first, followed by the anion.or monatomic anions, the element’s name is modified by adding the suffix “-ide.”or example, Cl⁻ becomes “chloride,” and Br⁻ becomes “bromide.”hen dealing with polyatomic ions, the specific name of the ion is used.
or metals that can form cations with different charges, Roman numerals are used to indicate the charge.or instance, iron can form Fe²⁺ (iron(II)) and Fe³⁺ (iron(III)) cations.owever, calcium and silver have fixed charges (Ca²⁺ and Ag⁺, respectively), so Roman numerals are not necessary in their compound names.
nderstanding the charges of ions and the rules for naming compounds is essential in chemistry.t ensures clear communication about the composition and structure of chemical substances.hese conventions are standardized to prevent ambiguity and facilitate the study and application of chemical principles.
