Where are the metals in the Periodic Table? Below the B (Boron) - Po (Polonium) staircase, in the bottom left corner of the Periodic Table. Before we start, though, I just wanted to review a few terms. The rest of metals have many oxidation states. Learning to name ionic compounds is both easy and hard depending on the complexity of the compound. How do I know what metals have more than one oxidation state? Metals of Group IA, Group IIA and aluminum (and some other exceptions) have only one oxidation state. Why do some cations require a roman numeral? Because they have more than one oxidation state (or charge), for example, Fe 2 and Fe 3 , iron (II) and iron (III) respectively. Ca 3N 2 is calcium nitride, and AlBr 3 is aluminum bromide. In TiO 2 the cation is titanium (IV) and the anion is oxide, hence the name is titanium (IV) oxide. They can be classified into three major classes as Type I: the metal can form only one type of cation. Every binary ionic compound will contain only two elements. For example, Na 2S is made of a cation sodium and an anion sulfide, hence the name is sodium sulfide. Binary ionic compounds: Ionic compounds that are made up of one cationic metal and anionic non-metal are called binary ionic compounds. The name of an ionic compound consists of the cation name plus the anion name. The name of a binary compound containing monatomic ions consists of the name of the cation (the name of the metal) followed by the name of the anion (the name of the nonmetallic element with its ending replaced by the suffix ide ). Binary ionic compounds are composed of two parts: a cation and an anion. Na 3P sodium phosphate sodium phosphorus sodium phosphite sodium phosphide trisodium phosphide sodium (I) phosphite Select one choice per compound and submit your answer. The other fluoride of tin is SnF 4, which was previously called stannic fluoride but is now named tin(IV) fluoride.Ĭhemists use nomenclature rules to clearly name compounds.Identify ions identify ions (one more exercise) identify ionic compounds identify ionic compounds (one more exercise) name binary ionic compounds name binary ionic compounds (one more exercise) name ionic compounds with polyatomic ions name ionic compounds with polyatomic ions (one more exercise) identify acids name acids name acids identify molecular compounds (one more exercise) name molecular compounds name ionic compounds, acids, and molecular compounds name ionic compounds, acids, and molecular compounds (one more exercise)Ĭhoose the names for binary ionic compounds below. Molecular compounds contain discrete molecules, which are held together by sharing electrons ( covalent bonding). Common salt (sodium chloride) is one of the best-known ionic compounds. The first element in the compound is named first, and the full. Ionic compounds contain ions and are held together by the attractive forces among the oppositely charged ions. This represents the formula SnF 2, which is more properly named tin(II) fluoride. Rules for Naming Type III Binary Compounds 1. For example, you may see the words stannous fluoride on a tube of toothpaste. Though this naming convention has been largely abandoned by the scientific community, it remains in use by some segments of industry. Binary ionic compounds are composed of just two elements: a metal (which forms the cations) and a nonmetal (which forms the anions). Out-of-date nomenclature used the suffixes – ic and – ous to designate metals with higher and lower charges, respectively: Iron(III) chloride, FeCl 3, was previously called ferric chloride, and iron(II) chloride, FeCl 2, was known as ferrous chloride. \): Names of Some Transition Metal Ionic Compounds Transition Metal Ionic Compound
