Name the compounds and win a Million! Ionic compounds are a type of chemical compound made up of metal cations (positive ions) and non-metal anions (negative ions). An air ioniser (or negative ion generator or Chizhevsky's chandelier) is a device that uses high voltage to ionise (electrically charge) air molecules.Negative ions, or anions, are particles with one or more extra electrons, conferring a net negative charge to the particle. You can recognize ionic compounds because they consist of a metal bonded to a nonmetal.

To name an ionic compound, you simply need to find the names of the cation and anion present in the compound and make sure to revise the ends of metal names as needed. Special ChemDoodle Offer. a) the net ionic equation of an ionic compound. As the elements progress from left to right, the electronegativity increases. The names have been separated into 2 types. Ionic bonds form between two atoms that have different electronegativity values.Because the ability to attract electrons is so different between the atoms, it's like one atom donates its electron to the other atom in the chemical bond. Fertilizers, Compound fertilizers containing two or all three of the three basic plant nutrients—N, P2Os, and K2O—as well as microelements, such as B, Mn, Cu, Zn, and Mo. the ions have the electronic structure of a noble gas (group 0 element), with a full outer shell. Sometimes a random word just isn't enough, and that is where the random sentence generator comes into play.
