Many gases are heavier than air and will spread along ground and collect in low or confined areas (sewers, basements, tanks). For each of the following questions, determine whether the compound is ionic or covalent and name it appropriately. Mixed Ionic/Covalent Compound Naming For each of the following questions, determine whether the compound is ionic or covalent and name it appropriately. 2) P2O5 diphosphorus pentoxide. Ionic compounds involve the transfer of electrons, while covalent compounds share electrons. When it is large, the bond is polar covalent or ionic. Keep unauthorized personnel away. For each of the following questions, determine whether the compound is ionic or covalent and name it appropriately. The absolute values of the electronegativity differences between the atoms in the bonds H–H, H–Cl, and Na–Cl are 0 (nonpolar), 0.9 (polar covalent), and 2.1 (ionic), respectively. Ionic and Molecular (Covalent) Compounds Naming and Formula Writing Review 1. 2) P2O5 diphosphorus pentoxide. Hydrogen (H) has an electronegativity of 2.1. Keep out of low areas. Ventilate closed spaces before entering. 1) Na2CO3 sodium carbonate. / 7) CoBr2 cobalt (II) bromide. Ionic compounds conduct electricity when dissolved in water, covalent compounds don’t. a. silicon tetrafluoride is Covalent bond I'll tell you the ionic or Covalent bond list below. A covalent crystal contains a three-dimensional network of covalent bonds, as illustrated by the structures of diamond, silicon dioxide, silicon carbide, and graphite. 3) I2 1) Na2CO3 sodium carbonate. 1) Na 2 CO ... silicon tetrafluoride SiF 4 20) silver phosphate Ag 3 PO 4 (Still) More Naming Practice - Answers 1) BBr 3 boron tribromide 2) CaSO 4 calcium sulfate 3) C 2 Br 6 In my research it appears that SiF4 has the characteristics of a covalent bond (colorless gas, odorous, soluble in water, and a low melting point). Write the formula for the following binary ionic compounds. 5) SiO2 silicon dioxide. 3) NH3 ammonia. 6) GaCl3 gallium chloride. Graphite is an exceptional example, composed of planar sheets of covalent crystals … 6) Explain why ionic compounds are formed when a metal bonds with a nonmetal but covalent compounds are formed when two nonmetals bond. 19) silicon tetrafluoride _____ 20) silver (I) phosphate _____ Nomenclature Practice Solutions. 4) FeSO4 iron (II) sulfate. When I went to determine if the bond was non polar or polar based on the electro-negativities, I found that SiF4 is an ionic bond. This surprised me because Silicon Tetrafluoride doesn't seem to have the characteristics of an ionic bond. Ionic/Covalent Compound Naming Solutions . Stay upwind. Ionic/Covalent Compound Naming Solutions For each of the following questions, determine whether the compound is ionic or covalent and name it appropriately. If you want to quickly find the word you want to search, use Ctrl + F, then type the word you want to search. Calcium phosphate: Covalent Bonding in Ionic Species 5.7 Ca2+ PO43– Ca3(PO4)2 Sum of charges: 3(+2) + 2(–3) = 0 Covalent Bonding in Ionic Species Covalent Bonding in Ionic Species Worked Example 5.9 Strategy Begin by identifying the cation and anion in each compound, and then combine the names for each, eliminating the word ion. Silicon (Si) has an electronegativity of 1.8.
