Chapter 6 - Answer Key to Section Review 1-3 Section Review 1 1. What is the main distinction between ionic and covalent bonding? Answer (A): Ionic bonding involves the electrical attraction between large numbers of anions and cations. Covalent bonding involves the sharing of electron pairs between two atoms. Translation: -Ionic bonding happens between a metal and a non-metal (east coast and west coast) -One atom completely donates its valence electrons to another atom -Metals

broadly classified into two types: Ionic and Covalent. Ionic: metal & nonmetal Metals have a tendency to lose electrons and nonmetals have a tendency to gain them. The metal atom becomes a cation and a nonmetal becomes an anion. The oppositely charged ions attract one another and form an ionic compound Covalent: nonmetal & nonmetal Covalent bonds are shared; Ionic bonds are distributed Covalent bonds are stronger than Ionic bonds Ionic Compounds: Ionic compounds consist of positive and

question. Which type of compound usually has higher melting points: ionic compounds or covalent compounds? What is the reason for this difference in melting points? (3 points) Link: http://misterguch.brinkster.net/covalentcompounds.html Answer: Ionic compounds have a higher melting point the heat needed to break down the bonds between the compounds is much higher than not needing to break down any bonds at all.

4 – Chemical Bonding: The Ionic Bond Model Study Questions Each question is worth 0.2 points. Total assignment is worth 5 points. 1. Describe the characteristics of ionic compounds and of molecular compounds. Ionic compounds have high melting points and conduct electricity well while covalent molecules have lower melting points and will not conduct electricity in a liquid state. 2. What types of particles are present as ionic bonds? Molecular compounds? Ionic bonding occurs between charged

Ferrous Nitrate of 0.5 M concentration) in an equal volume of water and relate this to the ionic radius of the element and the molar mass of the nitrate chosen and hence comment on the intermolecular forces in each of these nitrates. + write mass Justification of the research question: I was particularly interested in the difference in intermolecular forces of different nitrates and their relation with ionic radius. My imagination caught fire when I thought of this and thus I proceeded to conduct

Pre-Lab Work Sheet Which type of compound usually has higher melting points: ionic compounds or covalent compounds? What is the reason for this difference in melting points? (3 points) Ionic compounds have higher melting and boiling points than covalent compounds. The electrostatic attraction in an ionic bond is very strong hence a lot of heat energy is required to break it down‚ ionic bonds have high melting and boiling points. In covalent bonds‚ the intermolecular forces are very weak and

March 2‚ 2011 Lab Report Physical Properties of Two Types of Solids SCH3U0 Maggie Liu Abstract The purpose of this lab is to study some of the physical properties of two types of solids – ionic and molecular. The samples used are sodium chloride (ionic) and camphor (molecular). The physical properties studied are odour‚ hardness‚ melting point‚ solubility in water and solubility in 2-propanol. It is observed that some of the physical properties of sodium chloride are no odours‚ hard‚ a

Reactions in Aqueous Solutions: Metathesis Reactions and Net Ionic Equations Introduction: Metathesis or double decomposition reactions are a reaction in which two compounds react to form two new compounds‚ with no changes in oxidation number. The ions of two compounds exchange partners. AX + BY AY + BX This reaction can occur between two inorganic salts when one product is insoluble in water‚ driving the reaction forward. A typical example is as followed and is considered a molecular equation
