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

444 Cases E ot nearly a decade‚ the EU and the United I States were engaged in a heated trade dispute over bananas. The EU had introduced tariffs and quotas that discriminated in favor o[ bananas grown in former European colonies and dependencies located in the Caribbean and Africa.

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
