6) Explain why ionic compounds are formed when a metal bonds with a nonmetal but covalent compounds are formed when two nonmetals bond. Write the formula for the following binary ionic compounds. silicon tetrafluoride is Covalent bond I'll tell you the ionic or Covalent bond list below. Ionic/Covalent Compound Naming Solutions For each of the following questions, determine whether the compound is ionic or covalent and name it appropriately. Many gases are heavier than air and will spread along ground and collect in low or confined areas (sewers, basements, tanks). Ionic compounds involve the transfer of electrons, while covalent compounds share electrons. 7) CoBr2 cobalt (II) bromide. Ionic/Covalent Compound Naming Solutions . 1) Na2CO3 sodium carbonate. 1) Na2CO3 sodium carbonate. Ventilate closed spaces before entering. If you want to quickly find the word you want to search, use Ctrl + F, then type the word you want to search. Stay upwind. Ionic compounds conduct electricity when dissolved in water, covalent compounds don’t. 3) I2 For each of the following questions, determine whether the compound is ionic or covalent and name it appropriately. a. 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. 19) silicon tetrafluoride _____ 20) silver (I) phosphate _____ Nomenclature Practice Solutions. Silicon (Si) has an electronegativity of 1.8. When it is large, the bond is polar covalent or ionic. 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. Graphite is an exceptional example, composed of planar sheets of covalent crystals … 3) NH3 ammonia. Keep unauthorized personnel away. Ionic and Molecular (Covalent) Compounds Naming and Formula Writing Review 1. 5) SiO2 silicon dioxide. 2) P2O5 diphosphorus pentoxide. 2) P2O5 diphosphorus pentoxide. 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. / 6) GaCl3 gallium chloride. 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. A covalent crystal contains a three-dimensional network of covalent bonds, as illustrated by the structures of diamond, silicon dioxide, silicon carbide, and graphite. This surprised me because Silicon Tetrafluoride doesn't seem to have the characteristics of an ionic bond. 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). 4) FeSO4 iron (II) sulfate. 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 Keep out of low areas. Hydrogen (H) has an electronegativity of 2.1.
