Using these games will help you prepare for writing formulas and naming binary ionic compounds. NOTE: ALL NUMBERS IN FORMULAS SHOULD BE WRITTEN AS SUBSCRIPTS. 18. What is the formula of the compound that occurs when Beryllium and Nitrogen combine ionically? Be 3 N 2 19. What is the formula of the compound that occurs when Strontium and Chlorine combine ionically? SrCl 2 20. What is the formula of the compound that occurs when Aluminum and Oxygen combine ionically? Al 2 O 3 21. Apply knowledge of ionic bonding to predict the formula of ionic compounds. Key Points. Note that the cation always precedes the anion both in written form and in formulas. In the written form, while the cation name is generally the same as the element, the suffix of single-atom anions is changed to -ide...Other articles where Strontium oxide is discussed: crystal: Ionic bonds: … (CaS), barium selenide (BaSe), or strontium oxide (SrO). They have the same structure as sodium chloride, with each atom having six neighbours. Oxygen can be combined with various cations to form a large number of...the formula, CaH2. The names of binary ionic compounds follow the pattern: (name of element in cation) (root of name of element in anion) ide Thus, cesium bromide is CsBr and AlCl3 is aluminum chloride. Likewise, the formula for strontium fluoride is SrF2 and formula for aluminum sulfide is Al2S3.

Sodium carbonate is an ionic compound whose formula is NaCO3. A compound commonly called trisodium phosphate, Na3PO4, is used to clean grease and other organic materials from concrete surfaces.The bone and tooth enamel in your body contain ionic compounds such as calcium phosphate and hydroxyapatite. Predict the formula of calcium phosphate, which contains Ca 2+ and PO 4 3-ions. Calculate the value of x, if the formula of hydroxyapatite is Ca x (PO 4) 3 (OH). Click here to check your answer to Practice Problem 5 All nitrogen compounds contain both isotopes, but because of isotopic fractionation they are incorporated into compounds in differing ratios depending on the nature of the reactions that produce the compounds. For example, as nitrogen compounds are passed up the food chain, the lighter isotopes are excreted in urine and the heavier isotopes are ...
