Covalent compounds like beryllium sulphate have a higher enthalpy of dissociation than ionic barium sulphate. Polyatomic Ionic compounds 2. Based on the elements present in a chemical formula, classify the compound as ionic or covalent (covalent molecules are also referred to as molecular compounds). Nam. Writing and Balancing Chemical Equations The double tetrahedron structure (coordination) is sharing one oxygen anion O 2−, whereas in the Si-O-Si- molecular structure, the covalent bond is achieved through Si … Sodium chloride is an ionic compound. The difference in electronegativity between the two atoms in the bond can help predict whether the bond is likely to be ionic, covalent, or polar covalent, as can the type of atoms involved (metals or non-metals). Mixed Ionic/Covalent Compound Naming For each of the following questions, determine whether the compound is ionic or covalent and name it appropriately. Ionic 11. !

Electrolysis CSUS Chemistry 1A Nomenclature Worksheet Dr. Mack Page 3 of 9 S S2– sulfide ion IA H H– hydride ion Polyatomic Ions Polyatomic ions are ions that are composed of two or more atoms that are linked by covalent bonds, but that still have a net deficiency or surplus of electrons, resulting in an overall charge on the group. (In fact, it is ionic.) Uncombined elements have an oxidation state of 0. intermolecular forces are weaker than intramolecular forces. For example, sodium chloride melts at 801 °C and boils at 1413 °C. 2 Aluminum sulfate Ionic Al 2(SO4) 3 342.14 3 Diboron tetrabromide ionic B 2Br 4 341.22 4 Potassium chloride Ionic KCl 74.55 5 Sodium fluoride Ionic NaF 41.99 Sodium chlorite Ionic NaClO 2 90.44 7 Sulfur dioxide covalent SO 2 64.06 8 Ammonium Chloride Ionic NH 4Cl 53.50 9 Copper (II) oxide Ionic CuO 79.55 3. Reaction of Aluminum and Bromine There are three isotopes of hydrogen. For instance, hydrogen chloride, HCl, is a gas in which the hydrogen and chlorine are covalently bound, but if HCl is bubbled into water, it ionizes completely to give the H+ and Cl- of a hydrochloric acid solution. They can share electrons, making a covalent bond, or they can just borrow them, and make an ionic bond (also called electrovalent bond). There are three isotopes of hydrogen. Ionic compounds are (usually) formed when a metal reacts with a nonmetal (or a polyatomic ion). Thus, sodium hydroxide can be obtained by evaporating the water after the electrolysis is complete. 1 Aluminum has a Pauling electronegativity of 1.5 and bromine has an electronegativity of 2.8. The Model: Fe is the elemental form of iron. Chemical formula As the reaction proceeds, hydroxide ions replace chloride ions in solution. Predict which forms an anion, which forms a cation, and the charges of each ion. Compounds are classified as ionic or molecular (covalent) on the basis of the bonds present in them. Solid aluminum metal reacts with solid diatomic iodine to form solid Al 2 I 6. The usual chemical formula for water assumes the hydrogen atoms consist of the isotope protium (one proton, no neutrons). Naming Packet Answer Key - Ms. Demonte's Chemistry Classes Answers – Naming Chemical Compounds Covalent bonds are the attractive forces between the positively charged nuclei of the bonded atoms and one or more pairs of electrons that are located between the atoms. Covalent compounds Therefore, it is most likely an ionic compound. 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. Other forms of the chemical formula for water include D 2 O, … Acids, bases and salts. 2. ! So, BeSO 4 is more soluble than ionic BaSO 4. Which one of the following represents the net ionic equation for the reaction of nitric acid with aluminum hydroxide? Isotopes 16) vanadium (V) oxide V2O5. Remember, they may be either ionic or covalent compounds, so make sure you use the right method! CuC2H3O2 ... gold (III) chloride ! In contrast, the compound NO 2 contains two elements that are both nonmetals (nitrogen, from group 15 [or 5A], and oxygen, from group 16 [or 6A]. Alkanes, alkenes & alkynes. The resulting electronegativity difference of 1.3 for the aluminum-bromine bond falls well within the … TYPES OF COMPOUNDS Ionic compounds are compounds composed of ions, charged particles that form when an atom (or group of atoms) gains or loses electrons. 18) zinc sulfide ZnS So, let’s say we've got a sodium atom that has an extra electron. Ionic hydrides are used as bases and, occasionally, as reducing reagents in organic synthesis. As the reaction proceeds, hydroxide ions replace chloride ions in solution. 4. Ionic or Covalent Chemical Formula 1) copper (II) chlorite 2) sodium hydroxide 3) nitrogen dioxide 4) cobalt (III) oxalate 5) ammonium sulfide 6) aluminum cyanide 7) carbon disulfide 8) tetraphosphorous pentoxide 9) potassium permanganate … C is the elemental form of carbon. 12) nitrogen N2. 2. For each of the following questions, determine whether the compound is ionic or covalent and write the appropriate formula for it. Li 2S Metal and non-metal— ionic Lithium Sulfide NO (not di lithium sulfide— no prefixes for ionic compounds) N2O4 2 non-metals—covalent C 6 H 5 C(O)CH 3 + KH → C 6 H 5 C(O)CH 2 K + H 2. Other forms of the chemical formula for water include D 2 O, … 17) aluminum hydroxide Al(OH)3. covalent compound ionic compound USE GREEK PREFIXES Put prefixes in front of element names to tell how many atoms are there. 15) phosphorus trifluoride PF3. 9.

Common formula quiz. ... between two molecules whereas intramolecular forces involve the direct bonding of atoms for form molecules such as in covalent or ionic bonds. 3. Chemical suffixes. 14) lithium acetate LiC2H3O2. Nitric acid has the chemical formula HNO3, and Calcium Hydroxide has the chemical formula Ca(OH)2. Ionic compounds are solids that typically melt at high temperatures and boil at even higher temperatures. When they work together, they can both wind up happy! Heavy water is also possible, in which one or more of the atoms of hydrogen consist of deuterium (symbol D) or tritium (symbol T). 13) methane CH4. Name of Ionic Compound But the smaller entities like beryllium have higher charge density, resulting in higher solvation and hence, release of hydration enthalpy, larger than the dissociating energy. Typical solvents for such reactions are ethers. The naming of ionic compounds that contain polyatomic ions follows the same rules as the naming for other ionic compounds: simply combine the name of the cation and the name of the anion. Sodium hydroxide is valuable in its own right and is used for things like oven cleaner, drain opener, and in the production of paper, fabrics, and soap. It is not an ionic compound; it belongs to the category of covalent compounds discussed elsewhere. But the smaller entities like beryllium have higher charge density, resulting in higher solvation and hence, release of hydration enthalpy, larger than the dissociating energy. Write the formula for aluminum hydroxide. Name the following Covalent Compounds:! Name the following Ionic Compounds:!

The differences between the ionic concept (coordination) and the covalent bonding are profound. Covalent compounds like beryllium sulphate have a higher enthalpy of dissociation than ionic barium sulphate. 2 Al(s) + 3 Br 2 (l) ==> 2 AlBr 3 (s)Aluminum bromide is hygroscopic and fumes in air, forming a white cloud that looks orange because it is mixed with bromine vapor. When solid sodium chloride is added to aqueous sulfuric acid, hydrogen chloride gas and aqueous sodium sulfate are produced. potassium permanganate !!!

The sum of the oxidation states within a compound or ion must equal the overall charge. You can often recognize ionic compounds because of their properties. The usual chemical formula for water assumes the hydrogen atoms consist of the isotope protium (one proton, no neutrons). So, BeSO 4 is more soluble than ionic BaSO 4. Many bonds can be covalent in one situation and ionic in another. I. However, it is not always true (for example, aluminum chloride, AlCl 3, is not ionic). Nomenclature Worksheet 2: Simple Binary Ionic Compounds Please complete the following table: Formula of Ionic Compound s 2. Heavy water is also possible, in which one or more of the atoms of hydrogen consist of deuterium (symbol D) or tritium (symbol T). Sodium hydroxide is valuable in its own right and is used for things like oven cleaner, drain opener, and in the production of paper, fabrics, and soap. Add any text here or remove it. 1.
