CHEM 210 2023 with complete solution

Given the name endings below classify them as cation, monoatomic anion, polyatomic anion, metal element, and or nonmetal element 1. -ide 2. -ium 3. -ate 4. -ine 5. -ite 1. monatomic anion? 2. cation 3. polyatomic anion 4. nonmetal element 5. polyatomic anion monatomic vs polyatomic ions number of atoms What suffixes are used when oxygen is included in the formula? -ite and -ate How is the Roman numeral in ionic compounds related to the charge on the atoms? The Roman numeral is related to the charge needed to get the compound to a stable state Write the chemical name for this ionic compound 1. PbO2 lead (IV) oxide The formulas for elements never contain a subscript? (T or F) False All cations are... positive or negative? positive All anions are... positive or negative negative Does the first name of the ionic compound change in any way? For example, would Li be written as Lithium or Lithide? Lithium What is the suffix of the second name when naming an ionic compound? -ide Where on the periodic table would you expect to find elements that ionize to form cations? The left, metals What is the overall charge of ALL ionic compounds? (positive, negative or neutral) neutral Write the chemical name of these two ions 1. Cu3N 2. Cu3N2 1. copper (I) nitride 2. copper (II) nitride Transition metals can form cations with different charges under different circumstances? (T or F) T What is the charge on these two iron ions? 1. FeBr2 2. FeBr3 1. +2 2. +3 Given the chemical formula of an ionic compound, list three necessary steps to give the correct name of that compound. 1. identify metal (cation) 2. identify non-metal (anion) 3. add the proper suffix to the anion (-ide) Where on the periodic table would you expect to find elements that ionize to form anions? The right, non-metals For each ionic compound, identify the cation and the anion (+ or -) 1. sodium fluoride 2. barium chloride 1. +,- 2. +,- Predict whether the following will be cations or anions 1. magnesium ion 2. selenide ion 3. bromide ion 4. cesium ion 1. cation 2. anion 3. anion 4. cation When the name of an ionic compound is given, what is the ion stated first? (cation or anion) cation Classify as ionic or covalent 1. ZnCl2 2. N2O2 3. NaBr 4. CO 5. CoBr2 1. ionic 2. covalent 3. ionic 4. covalent 5. ionic Ionic vs covalent An ionic compound consists of a metal and a non-metal. Whereas covalent compounds, consist of two non-metals. Explain why elements can have subscript and not be considered compounds? Because the definition of a compound states that it must be more than one atom, therefore, even though S8 has 8 Sulfur because it is all the same atom it is classified as an element Identify the following as elements or compounds. 1. S8 (subscript) 2. Cl2 (subscript) 3. FeCl3 (subscript) 4. Fe 1. Element 2. Element 3. Compound 4. Element What types of metals require the use of Roman numerals in the name their ionic compounds? Transitons metals Polyatomic ions are a group of atoms that are held together by covalent interactions, the entire group of atoms carries the charge. (T or F) T What is the ending suffix when there is no oxygen atoms in the formula? -ide Why would it be unlikely for a solid material to be made entirely of pure carbonite ions? ...
