Name the element that forms compounds, under appropriate conditions, with every other element in the periodic table except He, Ne, and Ar. a. BaS b. FeCl3 c. PbI4 d. SrBr2 . h) Lithium oxide << Most cations and anions can combine to form solid compounds that are usually known as salts. a. BaS b. FeCl3 c. PbI4 d. SrBr2 . CC BY-SA. Give each ionic compound an appropriate name. Name the ionic compound formed by each pair of ions. 4. Writing names and formulas for ionic compounds.

Cr2S3 c. RbI d. BaBr2 But suppose you want to name the binary ionic compound CuO. If a metallic element has cations of different charges, which cation is used has to be indicated by its suffix (an older method) or by Roman numerals in parentheses after its name in writing (the Stock system). CC BY-SA 3.0. http://www.chem1.com/acad/webtext/intro/int-5.html Write a formula for the ionic compound that forms between each pair of elements. %%EOF Usually, the positively charged portion consists of metal cations and the negatively charged portion is an anion or polyatomic ion. 788 0 obj <>stream This particular resource used the following sources: http://www.boundless.com/ The cation has the same name as its element. Spell out the full name of the compound. For cations that take on multiple charges (typically transition metals), the charge is written using Roman numerals in parentheses immediately following the element name. Learn this topic by watching Naming Ionic Compounds Concept Videos. If either the cation or the anion was a polyatomic ion, the polyatomic ion name is used in the name of the overall compound. Give SrI2 ionic compound an appropriate name. Remember that transition metals can have multiple oxidation states, so you are required Finally, combine the two ions to form an electrically neutral compound. Q. a. BaS Q. The anion’s name is similar to the elemental name, but the ending of the name has been removed and replaced with “ide.”. For each of the following, determine whether the compound is ionic or covalent and write the appropriate formula for it. The polyatomic ion name stays the same. 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. Then either give the same or chemical formula as necessary for each problem below. Boundless Learning 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 … (zV�cߌ�ա. Name the cation by stating its charge as Roman numeral in a parenthesis after its elemental name if it is a multiply charged metal. The net charge of an ionic compound must be zero. When naming ionic compounds, the cation retains the same name as the element. Give the name from the formula or the formula from the name for each of the following hydrated ionic compounds.BeCl2 • 2H2O. Thus, in an ionic bond, one ‘bonder’ must have a positive charge and the other a negative one. Common, or trivial, names of compounds are sometimes used in informal conversations between chemists, especially older chemists. 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. In the cases of iron and copper, the Latin names of the elements are used (ferrous/ferric, cuprous/cupric). d) Calcium bromide. a. CuSO 4 ____ copper (II) ... Write formulas for the following ionic compounds containing polyatomic ions. In naming an ionic compound, we follow the steps below: 1. �/5��4��R�!f�|!��d�K�1g/SS��x(�Cf�t�)+���iQ`/�(/��{��Ƭ�3�%��G���s��D�7�)�x؜�\�8�d���P0PIP-_��V��:�^N���G.S�r��y'*y��]�p"���������F�c�r�4��h ��@�� �Hs��&BnF�>�y2u6�}��/��z(�1�ŋ!��7���Q�uցe�=��dUKҌ��}��D5�4��x�F0�[BT1j ��k& 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. BaS b. FeCl3 c. PbI4 d. SrBr2 The older method uses the suffixes -ous and -ic to denote the lower and higher charges, respectively. For example, Cu(NO3)2 is copper (II) nitrate, because the charge of two nitrate ions (NO3−1) is 2\cdot(-1) = -2. strontium iodide.
