Ionic compounds form when a metal loses electrons to a non-metal The resulting ions in the compound are held together by forces of attraction (opposite charges attract) When elements bond to form compounds, changes occur in the arrangement of electrons In ionic compounds, the atoms form ions by either losing or gaining electrons metals (cations) - lose electrons, becomes positive charged non-metals (anions) - gain electrons, become negative charged Ionic Compound does not exist an individual particles, millions of ions are tightly hold together in a crystal

Some metals are capable of forming two cations instead of just one:Common multivalent metals: Copper, Cu, 1,2 Iron, Fe, 2,3 Lead, Pb, 2,4 Manganese, Mn, 2,4 Tin, Sn, 2,4 Naming multivalent metals must use roman numeral:I, II, III, IV,V

Nick the Camel ate a Clam for Supper in PhoenixNumber of consonants = number of oxygenNumber of vowels = chargeNote: the negative charge on the polyatomic ion includes for the entire polyatomic group(NO3) Nitrate -1(CO3)  Carbonate -2(ClO3)  Chlorate -1(SO4)   Sulfate -2(PO4)   Phosphate -3Ammonia NH3 1+Hydroxide OH 1-Nitrite NO2 1-

Molecular or covalent compoundThese involved compounds formed by the interaction of 2 or more non-metalThere is no transfer of electrons, instead electrons are shared (force not strong enough to pull electrons away completely) When one pair of electrons is being shared, that forms a single bond If 2 pairs are shared, a double bond forms If 3 pairs are shared, a triple bond forms How many electrons a non-metal element needs, how many pairs of bonds the element will form Structural Formula:Ex. H-O-H

Diatomic Molecule: a molecule consisting of only two atoms of either the same or differentCommon names: Water, H2O, most common available molecular compound on Earth, the "universal solvent" Ammonium, NH4, window cleanser, production of fertilizer Nitric oxide, NO, air pollutant produced in the automobile engine Hydrogent Sulfide, H2S, invisible gas with a distinctive "rotten egg" odour Prefix: Mono,1 Di,2 Tri,3 Tetra,4 Penta,5 Replace the ending of the second element with "ide"
