COrdination compounds Question 9.1: Explain the bonding in coordination compounds in terms of Werner’s postulates. =Werner’s postulates explain the bonding in coordination compounds as follows: (i) A metal exhibits two types of valencies namely‚ primary and secondary valencies. Primary valencies are satisfied by negative ions while secondary valencies are satisfied by both negative and neutral ions. (In modern terminology‚ the primary valency corresponds to the oxidation number of the metal

Affixes an Compound Words AFFIXES An affix is a morpheme that is attached to a word stem to form a new word. Affixes may be derivational‚ like English -ness and pre-‚ or inflectional‚ like English plural -s and past tense -ed. They are bound morphemes by definition; prefixes and suffixes may be separable affixes. Affixation is‚ thus‚ the linguistic process speakers use to form different words by adding morphemes (affixes) at the beginning (prefixation)‚ or the end (suffixation) of words. TYPES

IONIC COMPOUNDS In chemistry‚ an ionic compound is a chemical compound in which ions are held together in a lattice structure by ionic bonds. Usually‚ the positively charged portion consists of metal cations and the negatively charged portion is an anion or polyatomic ion. Ions in ionic compounds are held together by the electrostatic forcesbetween oppositely charged bodies. Ionic compounds have high melting and boiling points‚ and they are hard and very brittle. Ions can be single atoms‚ as the sodium and chlorine in

and hyphens have evolved to support ease of reading in complex constructions; editors often accept deviations from them that will support‚ rather than hinder‚ ease of reading. The use of the hyphen in English compound nouns and verbs has‚ in general‚ been steadily declining. Compounds that might once have been hyphenated are increasingly left with spaces or are combined into one word. In 2007‚ the sixth edition of the Shorter Oxford English Dictionary removed the hyphens from 16 000 entries‚ such
