The Activity Series for metals is developed by experiment. * Each element on the list replaces from a compound any of the elements below it. The larger the interval between elements‚ the more vigorous the reaction. * The first five elements (lithium - sodium) are known as very active metals and they react with cold water to produce the hydroxide and hydrogen gas. * The next four metals (magnesium

The Elements of Fiction Plot‚ Setting‚ Character‚ Conflict‚ Symbol‚ and Point of View are the main elements which fiction writers use to develop a story and its Theme.

the individual elements. Although elements such as gold‚ silver‚ tin‚ copper‚ lead and mercury have been known since antiquity‚ the first scientific discovery of an element occurred in 1649 when Hennig Brand discovered phosphorous. During the next 200 years‚ a vast body of knowledge concerning the properties of elements and their compounds was acquired by chemists (a 1790 article on the elements). By 1869‚ a total of 63 elements had been discovered. As the number of known elements grew‚ scientists
