Write the formulas for the four ionic compounds that can be made by combining the cations Mg2+ and Fes+2.43 (a) (NH 4) 2 CO 3 (d) AlPO 4 (b) CaI 2 (e) AgCH 3 CO 2 4. BaS b. FeCl3 c. PbI4 d. SrBr2 The cation has the same name as its element. Its older name is cupric chloride. Think About It Make sure that the prefixes match the subscripts in the molecular strontium iodide. In both systems, the name of the anion ends in -ide. Sodium forms only a 1+ ion, so there is no ambiguity about the name sodium ion. Most cations and anions can combine to form neutral, solid compounds that are usually known as salts. For example, Cu(NO3)2 is copper (II) nitrate, because the charge of two nitrate ions (NO3−1) is 2\cdot(-1) = -2. d) Calcium bromide. For example, K+1 is called  the potassium ion, just as K is called the potassium atom. Positive to positive and negative to negative ionic bonds do not occur. Li + and N 3− Mg 2 + and P 3− Li + and P 3− 10. Then, identify the anion and write down its symbol and charge. a. SnO b. Cr2S3 c. RbI d. BaBr2. (adsbygoogle = window.adsbygoogle || []).push({}); In chemistry, an ionic compound is a chemical compound in which ions are held together by ionic bonds. Wikipedia The one overriding requirement is that the resulting compound must be electrically neutral: therefore the ions Ca2+ and Br– combine only in a 1:2 ratio to form calcium bromide, CaBr2. Ionic bonds form instead of covalent bonds when there is a large difference in electronegativity between the ions. g) Cesium iodide. 0 Or provide chemical formulas using proper chemcial symbols, parentheses when needed, and numbers immediately following as subscripts, as in the following format: sodium chloride would be NaCl and aluminum sulfate [Al 2 (SO 4) 3] would be expressed as Al2(SO4)3. CC BY-SA. h) Lithium oxide << 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. CC BY-SA 3.0. http://en.wikipedia.org/wiki/ionic%20compound, http://www.chem1.com/acad/webtext/intro/int-5.html, http://en.wikipedia.org/wiki/Naming_ionic_compounds%23Naming_simple_ionic_compounds, http://en.wikipedia.org/wiki/Ionic_compound, https://www.boundless.com/chemistry/textbooks/boundless-chemistry-textbook/, Convert between the chemical formula of an ionic compound and its name. Write a formula for the ionic compound that forms between each pair of elements. SnO b. Cr2S3 c. RbI d. BaBr2 Since the overall charge of an ionic compound is usually 0, then this tells us that the Fe must have a charge of 3+. Wikipedia The older method uses the suffixes -ous and -ic to denote the lower and higher charges, respectively. c) Aluminum sulfide. - 13064223 Name: _____ Per: _____ Directions: First quickly scan the worksheet and circle any metals (as a symbol or as a name) that is a transition metal. 4. This particular resource used the following sources: http://www.boundless.com/ 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. Wikipedia Fe 3 + and Br − Fe 2 + and Br − Au 3 + and S 2− Au + and S 2− 11. O. Boundless vets and curates high-quality, openly licensed content from around the Internet. a. CuSO 4 ____ copper (II) ... Write formulas for the following ionic compounds containing polyatomic ions. For ionic compounds, the first atom is the name of the element, and the second atom has an -ide suffix. In the cases of iron and copper, the Latin names of the elements are used (ferrous/ferric, cuprous/cupric). 788 0 obj <>stream The anion’s name is similar to the elemental name, but the ending of the name has been removed and replaced with “ide.”. By sticking to each other, they resolve, or partially resolve, their separate charge imbalances. The name of NaBr is sodium bromide and the name of SrF 2 is strontium ﬂuoride. h��U�nA��>�z_FB�l��H�D���8�=�[3��=���� ���յ�Z��J�dD�V� �V��4d��(�OI�y#?�M�b�?�����})?��y9?����lqq�n6M7�W}�}$��ل����|>�Cs+b�����*� Give each ionic compound an appropriate name. For each of the following, determine whether the compound is ionic or covalent and write the appropriate formula for it. Iron (Fe) can have more then 1 oxidation state, so the oxidation state must be specified in the name. Names of some ionic compounds. 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. Name the ionic compound formed by each pair of ions. If either the cation or the anion was a polyatomic ion, the polyatomic ion name is used in the name of the overall compound. To name any binary ionic compound, place the cation name ﬁrst, followed by the anion name.The name of Cs 2 O, then, is cesium oxide. So it is Fe3+. 9. Give each ionic compound an appropriate name.

This system is still used, although it has been officially supplanted by the more precise, if slightly cumbersome, Stock system. BaBr 2. For example, NaF is also known as sodium fluoride. Ionic compounds have high melting and boiling points, and they tend to be hard and brittle. Salts of [FeCl4]− in … Name the ionic compound formed by each pair of ions. a. BaS Q. Q. Its systematic name is copper (II) chloride, where copper’s oxidation number is indicated in parentheses. For example, CuCl2 indicates a molecule where one Cu2+ cation associates with two Cl– anions to form a neutral compound. Name the ionic compound formed by each pair of ions. Each compound will be named using the systematic nomenclature including, where necessary, appropriate Greek prefixes. Remember that transition metals can have multiple oxidation states, so you are required f) Silver chloride. b) Calcium fluoride. CC BY-SA 3.0. http://en.wikipedia.org/wiki/Ionic_compound 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. This compound is therefore, copper (II) nitrate. CC BY-SA 3.0. http://en.wikipedia.org/wiki/ionic%20compound Systematic names are formal names that are always used in print. 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. Boundless Learning The polyatomic ion name stays the same. Solution (a) nitrogen trifluoride (b) dinitrogen tetroxide. %%EOF h�bbdb� �����X$D2} ��� �+ b. FeCl3 Q. a) Sodium iodide.
