what area some caracteristics of polyatomic ionic compounds?

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.

Four as a stable compound, up to 5 or 6 for a polyatomic ion.

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.

OK first in English...(And then in Croatian for you)\n\n\nAn ionic crystal is a crystal consisting of ions bound together by their electrostatic attraction. \n\nThey are characterized by strong absorption of infrared radiation and have planes along which they cleave easily\n\n\nUredu...Na hrvatskom za tebe :-).....\n\nŠto su ionski kristali? ??\n\nSama riječ kaže da su to kristali u kojima su atomi povezani ionskom vezom. \n\n    Ionska veza je karakteristična za kristale sastavljene od pozitivnih i negativnih iona. U atomima koji se udružuju u ionsku vezu, vanjske energijske podljuske su samo djelomično popunjene. Tipični ionski kristali su alkalni halogenidi. U njima atom alkalijskog metala gubi, a atom halogenog elementa  dobiva elektron. Energija kohezije za ionske kristale je 5-10 eV, znači imamo kristalni sustav  u kojem ioni različitog naboja međudjeluju kulonskim silama.

All ionic compounds dissociate into respective +ve and -ve ions in aquous solutions.\n\nYou possibly want to know such compounds which give both +ve and -ve ions with more than 1 charge.\n\nYes salts of all alkline earth metals (+ve2) with ions of more than one atoms (CO3,PO4 etc) having more than 1 -ve charge dissociate in the way you need to know.

It is lithium Chloride i.e. LiCl\nIt is an covalent compound rather than being an ionic compound. It is define by FAJAN's rule

The formula would be Al2(CO3)3; the numbers are subscripts. \n\nLearn your charges for the polyatomic ions and for the other elements, it will really help.

You want us to calculate acitivites?\n\nYou need to determine the ionic strength and atomic radius in order to do that.

The compounds have a high lattice enthalpy, thus much energy is required to break to ions up in solution. The also have very low solubility products, that is the product of the compounds ions in a saturated solution.

If you mean NaCl (letter L at the end instead of number one), then, yes, sodium chloride is an ionic compound. In solid form it is NaCl(s), commonly known as table salt.\n\nIn case you're wondering, the formula NaCl is actually considered a "formula unit" rather than a "molecule." In solid form, ionic compounds are 3-D matrices of ions. But when dissolved or solvated in water, the ions become free floating Na+ and Cl- ions rather than individual NaCl units. A formula unit simply shows the lowest whole-number ratio of cations (positively charged ions) to anions (negatively charged ions) given by the formula. Sodium chloride's cation to anion ratio is one sodium cation Na+ per chloride anion Cl-, or 1 to 1.\n\nBy way of contrast, the formula H2O (for water) represents a molecule, because each molecule of water is a distinct unit.

Generally, the elements that form ionic bonds tend to have either very high or very low electronegativity. This means the Alkali metals, Alkaline Earth metals, and the Halogens, especially when reacting with each other.

You will not find ions along by themselves, they are paired with other ions, forming ionic compounds.\nSome ionic compounds are soluble, some are.  The ones that are can range in solubility based on the solvent, temperature, and other ions in solution.\n\nFor instance, NaCl is very soluble in water at room temperature, where as under the same conditions, Silver Chloride is considered insoluble.\n\nTherre are actually a set of solubility rules to determine whether an ionic compound is or is not soluble in water based on the ions that make it up.\nhttp://www.csudh.edu/oliver/chemdata/solrules.htm
