History of Metals Timeline Infographic

Infographic: History of Metals Timeline. The development of civilisation has relied heavily on the discovery of metals. Prehistoric man used metals to build tools and weapons and as our knowledge of metallurgy has developed, metals have played an essential role in the advancement of agriculture, transport and arts and craft – forging the path to today’s modern society.

calcium is an element with atomic nuer20. Stating reason

i) The atomic nuer of calcium is 20. Its electronic configuration is 2,8,8,2. The valency of calcium is +2. Hence it is a metal belong to the group 2. ii) The radius of calcium is smaller than potassium because both elements lie in the third period of the periodic table. Potassium lies to the left of calcium in the period, and atomic size decreases, going left to right due to increase in the

Metals Used in Coins and Medals - Coins of the UK

The pure metal is magnetic, and is noticeably yellower than some of the silvery metals such as chromium and aluminium. In 1965 the United States produced pattern coins in a 95% nickel 5% silicon alloy, but it appears that all specimens were melted down. More recently UK 5p and 10p coins have been issued in steel with nickel plating.
