(Example 2. GaAs CdLi h) BaBr2 ZnO NaH. The classification of a compound depends on the type of chemical bond between the elements in the compound. H2OC dihydrogen monoxide. The solvent is the substance present in the larger amount. In the case of O$_2$ it is found that the lowest energy state is one that has one electron in each of two orbitals. Ionic bonding, electrons are transferred before bond formation, forming an ion pair. Classify each compound as ionic or molecular. Write the cation symbol, then the anion symbol. Because oxygen atoms have two fewer electrons than the nearest noble gas, neon, they gain two electrons to form -2 ions. The ionic compounds contain atoms of metals and nonmetals that are bonded together by an ionic bond formed via the transfer of electrons between the atoms. The best guide to the covalent or ionic character of a bond is to consider the types of atoms involved and their relative positions in the periodic table. In order to find how ionic a bond is, you need to look at the differences in their electronegativity. A reaction may be classified as redox in which oxidation and reduction occur or nonredox in which there is no oxidation and reduction occurring. • Ionic compounds are composed of one or more cations paired with one or more anions. That is, the principal species in solution for strong electrolytes are ions, while the principal specie in solution. Classify the following as a) mixture or b) pure substance. The difference between ionic and covalent bonds is a bit ambiguous since the only truly nonpolar covalent bond occurs when two elements of the same atom bond with each other (e.
