<p> Ionic and Covalent compounds - Workshop Outline The PowerPoint presentation as well as this workshop outline will be available online at the SLC’s wikispace page. Check us out at sesciencelab.wikispaces.com </p><p>Compounds generally composed of NON METALS ONLY are called ______. Compounds composed of a combination of METALS AND NON METALS are called ______. One exception is______.</p><p>1. Which elements when bonded to each other form covalent bonds? A) argon and oxygen B) copper and carbon C) oxygen and sulfur D) potassium and cesium E) H & Na</p><p>2. Which substance below is most likely to possess covalent bonds?</p><p>A) PCl3 B) KBr</p><p>C) MgF2</p><p>D) ScCl3</p><p>E) SiO2</p><p>3. Which substance has ionic bonds?</p><p>A) Na2O</p><p>B) NCl3 </p><p>C) H2S</p><p>D) CO2</p><p>E) SiCl4</p><p>4. Predict the chemical formulas of the compounds formed by the following pairs of ions: A) Cu+ and S2- B) Fe3+ and O2- 2+ 2- C) Hg2 and CO3 2+ 3- D) Ca and AsO4 + 2- E) NH4 and CO3 Naming Ionic Compounds 1 1) Name the first element, THE METAL.(If it is a roman numeral element, undo the crisscross to find the roman numeral) 2) Name the second element and if it is a nonmetal, change the ending to ide. If it is a polyatomic, name it.</p><p>1) NaI 2) FeCl3 3)(NH4)2CO3</p><p>4) Ca(NO3)2 5) Mn2(SO4)3 6) MnSO4</p><p>7) MgS 8) MgSO4 9) Mg(HSO4)2</p><p>Naming Covalent Compounds 1) Name the 1st element, 2nd element –ide 2) Prefix used to tell how many of each element. Mono- is only used on the last element. No charges involved – Use prefixes</p><p>1) PF5 2) N2O4 3) SCl2</p><p>4) BH3 5) NO 6) NO2</p><p>7) N2O 8) N2O5 9) P4S6</p><p>Writing Covalent Compounds</p><p>Write the correct symbol for the element names. Use prefixes for your subscripts. DO NOT crisscross numbers.</p><p>1) boron trihydride 2) dicarbon tetrachloride 3) sulfur dioxide 4) sulfur trioxide 5) iodine heptafluoride 6) tetraphosphorus decaoxide 7) sulfur hexafluoride 8) dichlorine heptoxide 9) phosphorus pentafluoride</p><p>2</p>
