What are the differences in the physical characteristics of substances formed by ionic bonds and those...?

Ionic bonds are comprised of a metal and a non-metal.\nCovalent bonds are comprised of two bonded non-metals.

Well, obviously the donation of electrons from + to - atoms. Also, ionic compounds are soluble in water. Since ionic interactions are weak, they are weakly bound together.

Ionic compounds are basically defined as compounds where two or more ions are held next to each other by electrical attraction. One of the ions has a positive charge (called a "cation") and the other has a negative charge ("anion"). Cations are usually metal atoms, and anions are either nonmetals or polyatomic ions (ions with more than one atom).\n\nA molecular compound is made up of all non-metals. The bond that forms between the atoms is by the sharing of electrons, unlike ionic compounds, which are made by the transfer of electrons.\n\nIn the case of NaH, this is a ionic compount and this is a strong base. \n\nAcid is defined as a compound which donates a hydrogen ion (H+) to another compound (called a base). You can also see it this way: An acid is a proton donor and a base is a proton acceptor. The acid is said to be dissociated after the proton is donated.\n\nAbout naming of compounds, read the book. It's a long discussion.

the elements most likely to form ionic bonds have low ionization energies (such as the alkali metals and the alkaline earth metals, which form cations) or high electron affinities (such as halogens and oxygen, which form cations).

Element = Sodiuim.  It still retains its properties even at the atomic level.\n\nCompound = NaCl (Table Salt).  It consists of two chemically bonded elements.\n\nMixture = sand and sugar.  No chemical bonding occurs.

Well, it all depends on what kinds of atoms are involved.   For instance, a covalent bond between two atoms with very small radius is probably much greater than an ionic bond between two atoms with similar electronegative values.  What I mean is that comparing ionic and covalent bonds is a relative thing; there are many premises involved.

Like dissolves like...where you're looking at polarity.  Covalently bonded solutes usually dissovle in covalently bonded solvents, but not in very polar things like water.  Salts, which are ionically bonded, require very polar solvents (like water or liquid ammonia).  Polar functional groups on solute molecules mean you need similar polar groups on your solvent molecules.  Non-polar solutes like non-polar solvents.

ionic,the diference in electronegativity values is greater then 1.6.  the metal bonded to a non metal method is also correct

MgO and Al2O3 have greater ionic character than SiO2. A compound melts when the lattice breaks down and a lattice breaks down when the bonds holding it in place give way.\n\nIonic bonds are stronger than Covalent ones.\n\nThere are some amorphous forms of SiO2.\n\nYes, an insulator can conduct under such conditions.

1)ionic and covalent depend on the situation and are considered generally equal \n2)network bonds are a type of covalent bond\n3)metallic bonds are weaker (this one's kinda fuzzy)\n4)intermolecular are the weakest

the previous answer is deficient on the following points...\nelemental C has the atoms held together by covalent bonding\nNa, being a metal, has metallic bonding, not ionic. Ionic bonds occure BETWEEN a metal and a non metal such as Na with Cl.\nMetallic character decreases as you cross the periodic table, and increases as you go down the periodic table, so Na is more metallic than Fe\nnon metallic character does the opposite..\nSo from the list above, metallic character would be Na > Fe >C  > S > O\nNa is a metallic lattice while O2 exists as discrete molecules\nHope that helps

Covalent bond: are those which one or more pairs of electrons are shared by two atoms.\nCovalent chemical bonds involve the sharing of a pair of valence electrons by two atoms, in contrast to the transfer of electrons in ionic bonds. These bonds lead to stable molecules if they share electrons in such a way as to create a noble gas configuration for each atom. \n\nHydrogen gas forms the simplest covalent bond in the diatomic hydrogen molecule. The halogens such as chlorine also exist as diatomic gases by forming covalent bonds. The nitrogen and oxygen which makes up the bulk of the atmosphere also exhibits covalent bonding in forming diatomic molecules. \n\n\n\nIonic Bonds\nIn chemical bonds, atoms can either transfer or share their valence electrons. In the extreme case where one or more atoms lose electrons and other atoms gain them in order to produce a noble gas electron configuration, the bond is called an ionic bond. \n\nTypical of ionic bonds are those in the alkali halides such as sodium chloride, NaCl\n\n\nThe below reference has some diagrams which are helpful as well.

When atoms combine by covelant or ionic bonds, the resulting compound has properties that are different from those of the atoms.  For example, Sodium is a soft and very reactive metal, and Chlorine is a yellow-green poisonous gas, but when they combine ionically, the result is table salt: neither reactive nor poisonous.  This has to do with how the electrons are situated at the atomic level.  Often, bonding stabilizes the electrons and makes the resulting compound less reactive, which is why water will not react the way Hydrogen or Oxygen do.

In chemistry, an ionic compound is a chemical compound in which ions are held together in a lattice structure by ionic bonds. The positively charged ion is usually a metal ion and the negatively charged ion is non-metallic element or molecule.\n\nIons can be single atoms, as in common table salt sodium chloride, or more complex groups such as calcium carbonate. But to be considered ions, they must carry a positive or negative charge.\n\nThus, in an ionic bond, one 'bonder' must have a positive charge and the other a negative one. By sticking to each other, they resolve, or partially resolve, their separate charge imbalances. Positive to positive and negative to negative ionic bonds do not occur. (For a real world analogy, experiment with a pair of bar magnets.)

metals: give up electrons in ionic bonds. They also form metallic bonding.  sodium, potassium, lithium, to name just a few. There are a lot of metals\n\nnonmetals: this is more more difficult group to describe. They materials like to form covalent bonds--a joint sharing of two electrons. Both hydrogen and oxygen are nonmetals. But hydrogen gives up its electon in an ionic bond. For example HCl. It that repect it acts similar to a metal. Carbon is also a nonmetal\n\nMetaloid: silicon, germanium, boron, arsenic, antamony. These elements are right on the line between metals and nonmetals. As a result they make good semi conductors.

Ionic bonds are created by attraction of separated charges or differences in electronegativity.  This results in a dipole moment, which is a vector property, hence it is directional.

Ionic compound is usually non-metal reacting with metals.\nThat is positive ion forming a compound with negative ion.\nWe call the compound is ionic if the elements we've used have positive or negative charge.\n\nConvalent compunds have different story because they are sharing the electrons and they don't really have any charge.\n\nI don't know what you mean by exactly what kinds of elements make ionic compounds because almost all of them do! Except all the noble gases far right side of table will not react at all (Where there is argon).\n\nIt is that simple
