May 12, 2015 · Ionic and covalent bonds are stronger than metallic bond. The strength of an ionic bond depends on the size of the charge on each ion and on the radius of each ion. These types of bonds result in high elastic modulus and hardness, high melting points, low thermal expansion, and good chemical resistance.
Review for Quiz 2: Ionic and Covalent Compounds 1. Know and understand the definitions of: metal, non-metal, ionic compound, covalent (molecular) compound, binary compound and electrolyte. • ionic compounds are pure substances that form when metal and non-metal atoms are chemically bonded together by an ionic bond (electrostatic attraction). K-Br and Na-Cl are ionic bonds. • polar covalent bonds: Bonds that lie between the covalent and ionic limits given above will be called polar covalent bonds. For example, H2O is water, NH3 is ammonia, and NO is nitric oxide. By convention, the less electronegative element is written first in the...
NH4Br, ammonium bromide, is ionic and contains the NH4+ ion and Br- ions. A bond can be covalent, ionic or metallic. In covalent bonding electrons are shared, electrons are transferred in ionic bonding and electrons move about in a sea of electrons in metallic bonds.

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. 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 ... The O2- ions are each surrounded by three Ti4+ ions. Ionic bonds are the electrostatic attractions between positive and negative ions. An ionic compound is a three-dimensional network of alternating cations and anions that are mutually attracted to one another.
A. An ionic bond occurs when a metal atom and a nonmetal atom share a pair of electrons. B. All chemical bonds involve the sharing of electrons between two atoms. C. A covalent bond occurs when one or more electrons are transferred from a metal atom to a nonmetal atom. D.
Jun 29, 2018 · Covalent or molecular compounds can exist as crystals, though. Examples include sugar crystals and diamond. Ionic compounds tend to have higher melting and boiling points than covalent compounds. Ionic compounds tend to be hard and brittle while covalent compounds tend to be softer and more flexible.
(If teacher says its ionic then that's OK) B2O3 is more covalent than ionic the electronegativity difference is only 1.4 and boron is not a metal. It is best described as a giant covalent molecule.
