Metals are found in free State in nature. Example gold, silver etc. When metals react with oxygen it form oxide. 2Mg + O2 = 2MgO When metal react with water it form hydroxide and hydrogen gas. 2Na + 2H2O= 2NaOH + HE When metal react with dillute acid it form salts and hydrogen gas. Mg + 2HCl =MgCl2 + H2

The English language belongs to the West Germanic branch of the Indo-European family of languages. The closest undoubted living relatives of English are Scots and Frisian. Frisian is a language spoken by approximately half a million people in the Dutch province of Friesland, in nearby areas of Germany, and on a few islands in the North Sea.

English is a West Germanic language that originated from Anglo-Frisian dialects brought to Britain in the mid 5th to 7th centuries AD by Anglo-Saxon migrants from what is now northwest Germany, southern Denmark and the Netherlands. The Anglo-Saxons settled in the British Isles from the mid-5th century and came to dominate the bulk of southern Great Britain. Their language, now called Old English, originated as a group of Anglo-Frisian dialects which were spoken, at least by the settlers, in England and southern and eastern Scotland in the early Middle Ages, displacing the Celtic languages (and, possibly, British Latin) that had previously been dominant. Old English reflected the varied origins of the Anglo-Saxon kingdoms established in different parts of Britain. The Late West Saxon dialect eventually became dominant. A significant subsequent influence on the shaping of Old English came from contact with the North Germanic languages spoken by the Scandinavian Vikings who conquered and colonized parts of Britain during the 8th and 9th centuries, which led to much lexical borrowing and grammatical simplification. The Anglian dialects had a greater influence on Middle English.
