    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 are easily broken‚ hence lesser heat is required and thus covalent bonds have

    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

    Identifying Ionic Compounds Written by Ashleigh Lara. In our experiment we were given 5 different cations who’s mixture of anions ranged from five to three different solutions. At every single station we were given the following materials a spot plate‚ a dropper‚ and the chemicals used to mix with our main substance. Each substance received 3 drops of the different chemicals which were able to give us an observation of what the compound was made into. Many of our experiments color‚ texture and solubility

    together in a chemical bond‚ a link between two atoms resulting from the mutual attraction of their nuclei for valence electrons. All chemical bonds involve valence electrons‚ but the bonds are classified by the way in which electrons are distributed within the bonds. Ionic and Covalent Bonds We will be studying two types of chemical bonds in this module: ionic bonds and covalent bonds. Atoms can gain or lose electrons to become charged ions. They form ionic bonds‚ a chemical bond that results from electrostatic

    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

    Describe the difference between a mixture and a compound. A compound is a substance in which atoms of different elements are chemically held to one another. A mixture is a substance made by combining two or more different materials in such a way that no chemical reaction occurs. A mixture can usually be separated back into its original components‚ a compound cannot. Below are some examples of the differences between each. Compounds •Compounds are pure substances. •They are made up of two or more

    chemical bond is the result of a lure (attraction) between atoms or ions. The different sorts of bonds that a molecule contains will determine its physical properties‚ including melting point‚ hardness‚ electrical and thermal conductivity‚ and solubility. How do chemical bonds occur? Chemical bonding occurs when two atoms with unfull valence orbitals react and exchange or share electrons; the result is either a covalent bond (shared electrons so that each has a full shell) or an ionic bond (the
