a)  Fe         b)  PCl3         c)  P4         d)  Ar. This module describes an approach that is used to name simple ionic and molecular compounds, such as NaCl, CaCO3, and N2O4. On one side have the name of an ionic compound (e.g. In fact, the human body is approximately 0.15% sodium, with the average person having one-twentieth to one-tenth of a kilogram in their body at any given time, mostly in fluids outside cells and in other bodily fluids. The charge of the metal ion is determined from the formula of the compound and the charge of the anion. d)  HCN(aq) contains the polyatomic ion cyanide. For example, sodium chloride melts at 801 °C and boils at 1413 °C. Binary acids are named using the prefix hydro-, changing the –ide suffix to –ic, and adding “acid;” HCl is hydrochloric acid. Look at the label or ingredients list on the various products that you use during the next few days, and see if you run into any of those in this table, or find other ionic compounds that you could now name or write as a formula. The charges of cations and anions dictate their ratios in ionic compounds, so specifying the names of the ions provides sufficient information to determine chemical formulas. The name and the formula usually begin with the element that is more to the left on the periodic table. Below is a chemistry quiz on ionic compounds, names, and formulas, give it a shot and see if you understood all we covered in this topic on Ions. The use of so many sodium compounds in prepared and processed foods has alarmed some physicians and nutritionists. 15. Spell. This will be marked by the subscript "aq," as shown in the examples below. For example, although NO is often called nitric oxide, its proper name is nitrogen monoxide. 14. Each type of compound has its own rules for naming it. Binary acids are composed of hydrogen and one other element, while oxyacids contain hydrogen, oxygen, and another element. What about converting compound names into compound formulas? This allows processed food manufacturers to add sodium-containing substances to food mixtures and know that the compound will dissolve and distribute evenly throughout the food. This is the cobalt(II) cation. Ionic and molecular compounds are named using somewhat-different methods. Q. Exposure to small amounts of Cr(VI) can lead to damage of the respiratory, gastrointestinal, and immune systems, as well as the kidneys, liver, blood, and skin. • Create. Chemical Reactions and Equations, 6.1 Writing and Balancing Chemical Equations, Chapter 7. In cases like this, the charge of the metal ion is included as a Roman numeral in parentheses immediately following the metal name. This is cobalt. Recall that ionic compounds consist of a positively charged cation and a negatively charged anion. The first thing we need to do is figure out what kind of compound we are working with, as ionic and covalent compounds have very different naming systems. Examples are shown in Table 2. Give the proper formula for each name. Simple ionic compounds such as sodium nitrite (NaNO2) are added to cured meats, such as bacon and deli-style meats, while a compound called sodium benzoate is added to many packaged foods as a preservative. When only one atom of the first element is present, the prefix mono– is usually deleted from that part. 20. Give the formula and name for each ionic compound formed between the two listed ions. Naming chemical compounds from the molecular or ionic formula can be intimidating, but if you grab a Periodic Table and follow a few simple rules for naming compounds, you'll be a master at naming compounds in no time at all. (As a comparison, the molecular compound … Want to know how to name ionic compounds and covalent compounds? Give the proper formula for each diatomic element. If the metal can form ions with different charges, a Roman numeral in parentheses follows the name of the metal to specify its charge. Table 10 “Some Sodium Compounds Added to Food” is a partial list of some sodium additives used in food. Naming Covalent Compounds (or "Molecular Compounds") When Given the Formula Covalent compounds, often called "molecular compounds," consist of two non-metals; a non-metal / non-metal pair. Give the formula and name for each ionic compound formed between the two listed ions. To name an inorganic compound, we need to consider the answers to several questions.
