#POLYATOMIC ION BONDING HOW TO#

Recall that compounds desire a neutral, or zero, net charge.

Naming the Anion SecondДЄfter writing the name of the cation, you can place the name of the monatomic anion followed by the suffix вЂњide.вЂќ For example, the chemical formula KCl produces the name вЂњcalcium chloride.вЂќ Naming Transition Metal CationsД«ut things get a bit more challenging once you expand beyond groups one and two. Aluminum, zinc, scandium, and silver will usually have a charge of +3, +2, +3, and +1 respectively and therefore no not use roman numerals like other metals do. To name a compound containing a magnesium cation, which has a 2+ charge, you would start by writing вЂњmagnesium.вЂќДЄ few metals outside of these two groups also almost always carry the same charge. The name of its compound would thus begin with вЂњpotassium.вЂќ The same goes for group two. This steady trend means that compounds containing one of these elements will begin simply with its name.ДЇor instance, the potassium ion from group one always carries a charge of 1+.

Groups One and TwoД®lements found within the first and second groups on the periodic table always form ions with a charge equal to their group number. However, the specific naming conventions will vary between elemental groups. The cation, or the positively charged particle, always begins the compoundвЂ™s name. Either way, the binary ionic naming process will apply.Д¬ompounds of metals with halides or oxygen are usually ionic solids, which have a lattice connecting the cations and anions, held together with electrostatic forces. Or they may be composed of multiple atoms, respectively.

Binary Ionic CompoundsДЇirst, we will learn how to name binary ionic compounds. To name these compounds, you must consider their ion constituents. The ionic lattice ensures that each ion forms regular patterns with the oppositely charged ions surrounding it. These compounds arrange themselves into a вЂњlatticeвЂќ structure. The electrostatic attraction between the participants facilitates electron transfer between them. This interaction typically occurs between a metal, which carries positive charge, and a nonmetal, which carries negative charge. What are ionic compounds? Ionic compounds form when atoms or molecules attract others with opposite charges. Can stand alone as polyatomic cation and anion.Polyatomic Ionic Compound: each constituent contains atoms from more than one element.Binary Ionic Compound: has two constituents, each of which is comprised of atoms from a single element.Anion participant is almost always a non-metal.Cation participant is almost always a metal.Ionic bond: compounds formed by the transfer of electrons between cations and anions.Anion: positively charged ion formed when neutral atom loses electrons.Cation: positively charged ion formed when neutral atom loses electrons.Charge: found by subtracting (protons-electrons) changes during ionic bonding due to electron transfer.Ion: atom or group of atoms that possess an electric charge.Compound: substance containing molecules that consist of atoms from two or more chemical elements (can be ionic or covalent).We will derive names from the chemical formulas of binary and polyatomic ionic compounds. In this tutorial, you will learn about nomenclature and naming ionic compounds.
