Since the charge of gold is not ambiguous, we do not need to include a roman numeral in brackets for this compound. NiI 2 20. Thus, $$\boxed{\mathrm{diphosphorus \; pentoxide}} Pb 2 SO 4. Tags: Question 8 . Note that we only use the 'mono-' prefix if the element occurs second, e.g. Convert the following from name to formula or formula to name and state whether it is an ionic or covalent compound. To know the charge of the compound, we have to know the formal charge of the other atom. Q. For example, {eq}\rm SF_{6} Lead(IV) compounds are not generally ionic - the ion Pb4+ would be highly polarising and would lead to covalent bonding, PbF4 is the most ionic - it is a high melting solid with a structure like SnF4. Note that for both ionic and covalent compounds, we always suffix the compound name with an -ide for a single element. Answer =  TeCl4 (  Tellurium tetrachloride )   is Polar What is polar and non-polar? What is the correct name for FeCl_3? PbS 2. PbS 2. Pb 2 SO 4. Iron (I)... Names the following species: a) HIO4 b) BrO2- c)... What is the name for the compound P_4O_{10}? The bond may result from the electrostatic force of attraction between oppositely charged ions as in ionic bonds; or through the sharing of electrons as in covalent bonds . Earn Transferable Credit & Get your Degree, Get access to this video and our entire Q&A library. Answer =  SCN-  (Thiocyanate) is   Polar What is polar and non-polar? Formula Type Chemical Name CaO I Calcium oxide C 2 H 2 M Dicarbon dihydride LiOH I Lithium hydroxide SO 3 M Sulfur trioxide The first element is phosphorus and there are two atoms of phosphorus (di-), and the second element is oxygen, of which there are 5 (penta-). Pb(SO 4) 2. 3) 2 zinc bicarbonate / zinc hydrogen carbonate 17. Answer =  C2Cl4 (  Tetrachloroethylene )   is nonPolar What is polar and non-polar? P 2O 5 ous pentoxide 14. How would you know when an 'ionic' compound is actually covalent? Combining these two in such a way to make the overall charge 0 gives us: We note that there are no metals in this compound. Answer Key Ionic, Molecular, or an Acid (Honors Chemistry) Write which type of compound it is, whether the compound is ionic, molecular, or an acid. All rights reserved. 60 seconds . Structure. © copyright 2003-2020 Study.com. Answer =  AsH3  ( Arsine )  is  Polar What is polar and non-polar? mercury (II) sulfate. SnBr 4 tin (IV) bromide 18. Q. MgCl 2 magnesium chloride For example, {eq}Fe_{2}O_{3} Since iodine has no prefixes, there is only 1 iodine atom. Answer : Lead (II) Sulfate ( PbSO4 ) is an Ionic bond What is chemical bond, ionic bond, covalent bond? Choose the appropriate number of atoms contained... What is the IUPAC name for the chemical formula... What is the IUPAC name for the compound FeS? When you have more than one polyatomic ion use parentheses! Q. The (IV) tells us that Lead has a charge of +4. Metals often have low electron affinities and therefore are more likely to bond with another species through ionic bonding. Choose the name-formula pair that does not match. $$. 1.9k plays . What is the formula for lead(IV) sulfate? These electron pairs are known as shared pairs or bonding pairs, and the stable balance of attractive and repulsive forces between atoms, when they share electrons, is known as covalent bonding. If there is a multi-valent metal present, write both the stock and classical name. Ionic & Covalent Compounds Complete this worksheet after reviewing Vocabulary Lessons 1-7 (in the Appendix). Answer =  ICl3  (Iodine trichloride)  is  Polar What is polar and non-polar? Since we are given the Roman numeral 4 in front of lead, we know that lead has a charge of 4, i.e. - Definition, Method & Practice Problems, The Activity Series: Predicting Products of Single Displacement Reactions, Ions: Predicting Formation, Charge, and Formulas of Ions, Electron Orbital: Definition, Shells & Shapes, What is a Diatomic Element? The ions are atoms that have gained one or more electrons (known as anions, which are negatively charged) and atoms that have lost one or more electrons (known as cations, which are positively charged). A chemical bond is a lasting attraction between atoms, ions or molecules that enables the formation of chemical compounds. Gold is a metal, therefore, this compound is ionic. Formula Type Chemical Name CaO I Calcium oxide C 2 H 2 M Dicarbon dihydride LiOH I Lithium hydroxide SO 3 M Sulfur trioxide Therefore, as a general rule, we can assume that the compound is ionic if it contains a metal bonded to a non-metal. {eq}\rm Pb^{4+} Question =  Is C2Cl4 polar or  nonpolar   ? https://en.wikipedia.org/wiki/Covalent_bond. Answer =  C4H10 (  BUTANE )   is Polar What is polar and non-polar? how much each atom wants to "keep" its electrons for itself. What is the accepted IUPAC name for the compound... What is the correct IUPAC name for the compound... What are the IUPAC names for Fe2O3 and MgO? 45 seconds . Ionic bonding is a type of chemical bond that involves the electrostatic attraction between oppositely charged ions, and is the primary interaction occurring in ionic compounds. Answer =  CLO3-  (Chlorate)  is  Polar What is polar and non-polar? I thought that BeCl2 should be ionic, but it is actually covalent. Name this compound: Be(NO 2) 2. answer choices ... Mixed Ionic and Covalent Naming . I thought that BeCl2 should be ionic, but it is actually covalent.
