What are the characteristics of ionic, atomic, covalent and metallic bonds?

i have to disagree...\n\nthere is an atomic bond. it is the general term for, well, chemical bonding.\n\nthe types of atomic bonds are: ionic, covalent, metallic...\n\nionic bond- it is the bond that involves movement of electrons. it normally is the bond between a nonmetal (positively charged; found at the left side of the periodic table ladder) and a metal(negatively charged; found at the right side of the ladder). example: NaCl, FeO, MgO, etc...\n\ncovalent bonding- this involves the SHARING of electrons. this may be called non-metallic bonding because it is the formation of substances by bonding nonmetals such as C, O, N, S (those found at the right side of the ladder). examples: CO, CO2, NO, HF, CH4, etc...\n\nmetallic bonding- from the name itself, it is the bond between two metals. this may relate through alloying (the combination of metals). It involves the delocalized sharing of free electrons among a lattice of metal atoms.\n\n\nhope this helps...:-)

Atoms are the smallest pieces of an element that still exhibit that element's properties.  They consists of a nucleus (protons and neutrons) and  electrons.  A hydrogen atom doesn't even have a neutron.\nA molecule is a combination of atoms of at least two different elements.  These atoms share at least one electron through a covalent bond.  The molecule will exhibit some of the properties of each of its ingredient elements, as well as some of its own unique properties.\nA neutral atom or group of atoms has no charge. It is neither a positive nor negative ion.\nAn ion is an atom or group of atoms that has either more or less electrons than it has protons.  If its number of electrons is greater that its number of protons, then it has a negative ionic charge, in the amount of the difference.  If its number of protons is greater than its number of electrons, then it has a positive ionic charge, in the amount of the difference.

Ionic compounds try to achieve the same thing...only instead of atoms sharing electrons with other atoms (co-valent) in a chemical bond, Ionic compounds achieve lowest energy configurations by receiving, or giving up, electrons.  For example, the sodium atom has one electron in it's valence "shell" and will give it up (becoming positively charged in the process) in order to have the same electronic configuration as the previous noble gas (neon) and becomes the sodium cation.\nFluorine, having seven electrons in it's valence shell would rather accept and electron (to have the neon electron configuration) and becomes the negatively charged fluoride anion.

interesting answer above.\n\nCarbon has 4 valance electrons which because of the relatively small size of the atom can move about and create all sorts of hybrid orbitals and molecular bonding orbitals allowing it to suit the bonding needs of many other atoms, thus making many varied combinations.\n\nIt is also in the middle range of electronegitivities therefore resisting in most situations becoming an ion.

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).

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.

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.

In covalent, atoms share electrons, but in ionic, one atom gives them to the other.  So in an ionic compound, there is a positive ion and a negative ion.  They ions can separate when put in water, and then the electricity can pass through.  Covalent compounds don't have a positive pole and a negative pole, and they don't ionize in water.  Also, the ionic bond is kinda stronger, so usually the compound is solid at room temperature (salt is ionic, oil is covalent).  You have to know that there is a third category, a polar molecule (like water).

Metallic bonding is the bonding within metals. It involves the delocalized sharing of free electrons between a lattice of metal atoms. Thus, metallic bonds may be compared to molten salts.\n\ne.g. Iron (Fe)... Why is it so strong? Of course, metallic bonding.\n\nMetal atoms typically contain a small amount of electrons in their valence shell compared to their period or energy level. These become delocalised and form a Sea of Electrons surrounding a giant lattice of positive ions.\n\nMetals seem to have higher boiling and melting points which might suggest stronger bonds between the atoms.\n\nMetallic bonding, as with covalent bonding is non-polar, in that there is no (for pure elemental metals) or very little (for alloys) electronegativity difference among the atoms participating in the bonding interaction, and the electrons involved in that interaction are delocalized across the crystalline structure of the metal.\n\nThe metallic bond accounts for many physical characteristics of metals, such as strength, malleability, ductility, conduction of heat and electricity, and luster. See also chemical bond.\n\nMetallic bonding is the electrostatic attraction between the metal atoms or ions and the delocalised electrons. This is why atoms or layers are allowed to slide past each other, resulting in the characteristic properties of malleability and ductility.\n\nMetallic bond are different from chemical bonds. Ionic and covalent bonds are chemical bonds.\n\nCovalent bonding is a common type of bonding, in which the electronegativity difference between the bonded atoms is small or non-existent. In the latter case, the bond is sometimes referred as purely covalent. See sigma bonds and pi bonds for current LCAO-explanation of non-polar bonds.\ne.g. CH4 (methane)\n\nIonic bonding is type of electrostatic bond between atoms which have an electronegativity difference of over 1.6 (this limit is a convention). These form in a solution between two ions after the excess of the solvent is removed.\ne.g. NaCl (common salt)\n\n<BEST ANSWER>\n============================================================\nHey, I tried to draw the structures of NaCl and methane molecules but this Yahoo! made it impossible. I hope you know the structurel.

Ionic bonds are a type of chemical bond based on electrostatic forces between two oppositely-charged ions.\n\nCovalent bonding is a description form of chemical bonding that is characterized by the sharing of one or more electrons between two atoms. In general bonds are defined by a mutual attraction that holds the resultant molecule together. Often bonding occurs in such a way that the the outer electron shells of the participating atoms becomes filled. Such bonds are always stronger than the intermolecular hydrogen bond and similar in strength to or stronger than the ionic bond......;

I2 is has a covalent molecular bond, that forms into the solid crystal.  So, that would be molecular. (Molecules make up the crystal structure).\n\nNi(s) is a crystal made up of atoms, so that's atomic.\n\nNone are ionic, b/c all the atoms in the crystal are the same, so they share electrons, they don't transfer them.

in covalent compounds, the two ions being bonded share electrons.  these are called covanlence electrons.  in an ionic bond, they share the electrons in a different way.

Any two elements from different sides of the periodic table. More specifically, one from the metal category and one from the nonmetal category.\n\nEDIT: brwneyes, sodium chloride is one example of an ionic bond, not the only kind of ionic bond.
