Work Session 2b: Formulas, Names, and Masses Use the information in your textbook for this work session, as well as the information on pages 4 and 5. Ionic compounds form when positive and negative ions share electrons and form an ionic bond.The strong attraction between positive and negative ions often produce crystalline solids that have high melting points. Wikipedia Usually, the positively charged portion consists of metal cations and the negatively charged portion is an anion or polyatomic ion. f) Silver chloride. Q. b.

Give SrI2 ionic compound an appropriate name. Common, or trivial, names of compounds are sometimes used in informal conversations between chemists, especially older chemists. b) Calcium fluoride. Its systematic name is copper (II) chloride, where copper’s oxidation number is indicated in parentheses. Its older name is cupric chloride. Determine whether the metal in the ionic compound BaO forms only one type of ion or more than one type of ion and name the compound accordingly. 4. (zV�cߌ�ա. 3. and (b) N. 2. The cation has the same name as its element. CC BY-SA. The “ine” was removed and replaced with “ide.” To name a compound, the cation name and the anion named are added together. Step-by-Step Solution: Step 1 of 3. Give the name and formula of the compound formed from the following elements: (a) cesium and bromine; (b) sulfur and barium; (c) calcium and ﬂuorine. Wikipedia 4. Ions can be single atoms, as the sodium and chlorine in common table salt (sodium chloride), or more complex groups such as the carbonate in calcium carbonate. For example, K+1 is called  the potassium ion, just as K is called the potassium atom. For cations that take on multiple charges (typically transition metals), the charge is written using Roman numerals in parentheses immediately following the element name. Since some metallic elements form cations that have different positive charges, the names of ionic compounds derived from these elements must contain some indication of the cation charge. In the cases of iron and copper, the Latin names of the elements are used (ferrous/ferric, cuprous/cupric). The Roman numerals in fact show the oxidation number, but in simple ionic compounds this will always be the same as the metal’s ionic charge. Write a formula for the ionic compound that forms between each pair of elements. Then, identify the anion and write down its symbol and charge. For example, Cu(NO3)2 is copper (II) nitrate, because the charge of two nitrate ions (NO3−1) is 2\cdot(-1) = -2. Solution (a) nitrogen trifluoride (b) dinitrogen tetroxide. Give each ionic compound an appropriate name. Names of some ionic compounds. Iron (Fe) can have more then 1 oxidation state, so the oxidation state must be specified in the name. Spell out the full name of the compound. The anion’s name is similar to the elemental name, but the ending of the name has been removed and replaced with “ide.”. This compound is therefore, copper (II) nitrate. Boundless Learning h�b��,y� ���� All Chemistry Practice Problems Naming Ionic Compounds Practice Problems. For example, NaF is also known as sodium fluoride. (adsbygoogle = window.adsbygoogle || []).push({}); In chemistry, an ionic compound is a chemical compound in which ions are held together by ionic bonds. But to be considered an ion, they must carry a positive or negative charge. Part 1: Binary Ionic Compounds Give the formula and name for the ionic compound formed between each of these metals with each of these nonmetals: Metals: sodium, magnesium, aluminum This system is still used, although it has been officially supplanted by the more precise, if slightly cumbersome, Stock system. Name the element that forms compounds, under appropriate conditions, with every other element in the periodic table except He, Ne, and Ar. Boundless vets and curates high-quality, openly licensed content from around the Internet. %PDF-1.5 %���� Each compound will be named using the systematic nomenclature including, where necessary, appropriate Greek prefixes. So it is Fe3+. But suppose you want to name the binary ionic compound CuO. Ionic, or saltlike, amides are strongly alkaline compounds ordinarily made by treating ammonia, an amine, or a covalent amide with a reactive metal such as sodium. In chemistry, an ionic compound is a chemical compound composed of ions held together by electrostatic forces termed ionic bonding.The compound is neutral overall, but consists of positively charged ions called cations and negatively charged ions called anions.These can be simple ions such as the sodium (Na +) and chloride (Cl −) in sodium chloride, or polyatomic species such as the … In this video, we'll walk through this process for the ionic compound calcium bromide. When naming ionic compounds, the cation retains the same name as the element. Most cations and anions can combine to form solid compounds that are usually known as salts. %%EOF e) Strontium oxide. Since the overall charge of an ionic compound is usually 0, then this tells us that the Fe must have a charge of 3+. The anion is named by taking the elemental name, removing the ending, and adding “ide.” For example, F-1 is called fluoride, for the elemental name, fluorine. To find the formula of an ionic compound, first identify the cation and write down its symbol and charge. Remember that transition metals can have multiple oxidation states, so you are required For example, CuCl2 indicates a molecule where one Cu2+ cation associates with two Cl– anions to form a neutral compound.
