naming ionic and molecular compounds

Ionic compounds are made up of a metal cation (named first) and a non-metal anion (named second). In the environment, chromium exists primarily in either the Cr(III) or Cr(VI) forms. Therefore the positive ions must be Fe3+, Cu2+, Ga3+, Cr3+, Ti3+ and Co3+. We have already mentioned that citrus fruits contain acid; among other compounds, they contain citric acid, H3C6H5O7(aq). a) K+ and SO42− b) NH4+ and S2− c) NH4+ and PO43−. Formulas of Molecular Compounds • Sodium is also present in our diet. a) NH4+ and S2− b) Al3+ and PO43− c) Fe2+ and PO43−. Remember, they may be either ionic or covalent compounds, so make sure you use the right naming method! Oxyacids are named by changing the ending of the anion to –ic, and adding “acid;” H2CO3 is carbonic acid. 20. Solution Log in Sign up. Chemical Reactions and Equations, 6.1 Writing and Balancing Chemical Equations, Chapter 7. You can find metals on the left and central sections of the periodic table (e.g., Barium, Radium, and Lead), while you can find non-metals on the right side of the table. Ionic compound nomenclature or naming is based on the names of the component ions. Find the ratio of positive ions to negative ions that results in a net charge of zero. The name of an ionic compound also gives you information about the oxidation numbers of the elements. Learn. This will be marked by the subscript "aq," as shown in the examples below. Thus, FeCl2 is iron(II) chloride and FeCl3 is iron(III) chloride. What are the IUPAC names of the following compounds? binary compound: compound containing two different elements. 1. The oxyacid suffix replacements are. Thus, NaCl = sodium chloride. To name an inorganic compound, we need to consider the answers to several questions. These are usually negatively charged "clumps" or "chunks" of ions that form bonds to the oppositely charged ion (usually a cation). Each of these two types of compounds has its own naming system and Lewis dot structure. Tags: Question 6 . Examples include SF6, sulfur hexafluoride, and N2O4, dinitrogen tetroxide. 4. Naming compounds that contain metals with multiple charges is done much the same way as naming other ionic compounds with one crucial difference: the charge of the metal is included in the compound name using roman numerals. a) XeF2 b) O2F2 c) SF6. Write the formulas of the following compounds: a) chlorine dioxide b) dinitrogen tetraoxide c) potassium phosphide, d) silver(I) sulfide e) aluminum nitride f) silicon dioxide. a) dioxygen dichloride b) dinitrogen trisulfide c) xenon tetrafluoride. 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. Write the proper formula and give the proper name for each ionic compound formed between the two listed ions. Upgrade to remove ads. False. We have discovered how to change chemical formulae into names of chemicals. SURVEY . c) Neither charge is an exact multiple of the other, so we have to go to the least common multiple of 6. Some metal cations can have multiple charges. Give the formula and name for each ionic compound formed between the two listed ions. CHEM 1114 - Introduction to Chemistry by Shirley Wacowich-Sgarbi is licensed under a Creative Commons Attribution-NonCommercial-ShareAlike 4.0 International License, except where otherwise noted. If only it were that easy. you ask… Well it's also possible to have ionic compounds that contain polyatomic ions. left of the metalloid staircase), it is a metal and the compound is "ionic." b) Because this acid is derived from the sulfate ion, the name of the acid is the stem of the anion name + -ic acid. CO is a compound of carbon and oxygen; Co is the element cobalt. If the compound is molecular, does it contain hydrogen? Here's how... Start by examining the chart below and visualizing how we convert "compound formulas" into "compound names.". Write. Enclosing the formula for the ammonium ion in parentheses, we have (NH4)2S. a) N2O b) N2O4 c) N2O5. Covalent compounds, often called "molecular compounds," consist of two non-metals; a non-metal / non-metal pair. The bonding characteristics of inorganic molecular compounds are different from ionic compounds, and they are named using a different system as well. left of the metalloid staircase), it is a metal and the compound is "ionic.". Usually sodium compounds are inexpensive, but, more importantly, most ionic sodium compounds dissolve easily. Formulas of Ionic Compounds • You should commit to memory the common names of compounds as you encounter them. Give the formula and name for each ionic compound formed between the two listed ions. 10. First, is the compound ionic or molecular? This is not current practice in most areas of the scientific community and we will not discuss it here. The name of a binary molecular compound ends in “ide”, just like the name of a binary ionic compound. (When an ion consists of more than one element, we … Ionic compounds consist of cations (positive ions) and anions (negative ions). This module describes an approach that is used to name simple ionic and molecular compounds, such as NaCl, CaCO3, and N2O4. For example, in sodium chloride, sodium is the cation element and chlorine is the anion element. An ionic compound always has two parts. Naming compounds have never been so simple! In ionic compounds, the ions are held together due to electrical attraction, whereas, in molecular compounds, the atoms are held together by the attraction between the atoms due to shared electrons. 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. Naming Ionic Compounds, Naming molecular compounds. 2. For binary ionic compounds (ionic compounds that contain only two types of elements), the compounds are named by writing the name of the cation first followed by the name of the anion. If so, does it also contain oxygen? Only use numerical prefixes for the first element when the molecule contains more than one of that atom. Most of the transition metals can form two or more cations with different charges. Test. The key difference between ionic and molecular compounds is that the ionic compounds have electrostatic attraction forces between cations and anions whereas the molecular compounds have only covalent chemical bonds between the atoms.. Chemical elements can join with each other to form chemical compounds. Some of the worksheets below are Naming Compounds Worksheets : Covalent Compound Names and Formulas, Ionic & Covalent Compound Naming, Formulas and nomenclature of ionic and covalent compounds, Covalent Compounds Worksheet : Questions like Based of the properties of the following materials, determine whether they are made of primarily ionic compounds of covalent compounds… Naming compounds that contain metals with multiple charges is done much the same way as naming other ionic compounds with one crucial difference: the charge of the metal is included in the compound name using roman numerals. Acids are an important class of compounds containing hydrogen and having special nomenclature rules. There are some exceptions to the general naming method (e.g., H2SO4 is called sulfuric acid, not sulfic acid, and H2SO3 is sulfurous, not sulfous, acid). STUDY. Q. Note that the definition of acid includes dissolved in water. Log in Sign up. (And H2O is usually called water, not dihydrogen monoxide.) Give the formula and name for each ionic compound formed between the two listed ions. 10. a) phosphorus trifluoride b) tellurium dichloride c) dinitrogen trioxide, 11. a) xenon difluoride b) dioxygen difluoride c) sulfur hexafluoride, 12. a) dinitrogen monoxide b) dinitrogen tetroxide c) dinitrogen pentoxide, 13. a) N2O5 b) B4C3 c) PCl5, 14. a) O2Cl2 b) N2S3 c) XeF4, 15. a) IF3 b) XeO3 c) S2F10, 17. a) hydrofluoric acid b) nitric acid c) oxalic acid, 18. a) cesium chloride b) barium oxide c) potassium sulfide, d) beryllium chloride e) hydrogen bromide f) aluminum fluoride, 19. a) RbBr b) MgSe c) Na2O d) CaCl2 e) HF f) GaP g) AlBr3 h) (NH4)2SO4, 20. a) ClO2 b) N2O4 c) K3P d) Ag2S e) AlN f) SiO2, 21. a) chromium(III) oxide b) iron(II) chloride c) chromium(VI) oxide, d) titanium(IV) chloride e) cobalt(II) oxide f) molybdenum(IV) sulfide, 22. a) K3PO4 b) CuSO4 c) CaCl2 d) TiO2 e) NH4NO3 f) NaHSO4, 23. a) manganese(IV) oxide b) mercury(I) chloride c) iron(III) nitrate, d) titanium(IV) chloride e) copper(II) bromide, binary acid: compound that contains hydrogen and one other element, bonded in a way that imparts acidic properties to the compound (ability to release H+ ions when dissolved in water). Write the charges on the ions. Oxalic acid, H2C2O4(aq), is found in spinach and other green leafy vegetables. Nomenclature, a collection of rules for naming things, is important in science and in many other situations.This module describes an approach that is used to name simple ionic and molecular compounds, such as NaCl, CaCO 3, and N 2 O 4.The simplest of these are binary compounds, those containing only two elements, but we will also consider how to name ionic compounds containing … Is not current practice in most areas of the first element in the format [.
