Periodic Table Elements such as gold and silver have been known since the earliest times. In 1649‚ a German alchemist‚ Hennig Brand made the first scientific discovery of an element‚ phosphorous. In the next 200 years‚ knowledge about the properties of elements and their compounds was gained. By 1869‚ 63 elements had been discovered in total. Scientists began to categorise those elements according to the similarities of their physical and chemical properties‚ which become the modern Period table we

Controlled experiment was conducted in UWA with a total of 34 participants to test the hypotheses. Complete records of the keys being pressed and the millisecond timing were captured by using a logging tool known as User Action Recorder (UAR). These keystroke data were then recovered into digraphs according to their types. Spearman Rank Correlation Test was performed for each

DEVELOPMENT OF THE PERIODIC TABLE Although Dmitri Mendeleev is often considered the "father" of the periodic table‚ the work of many scientists contributed to its present form. Elements such as gold‚ silver‚ tin‚ copper‚ lead and mercury have been known since earliest times. In 1649 the first scientific discovery of an element occurred. Hennig Brand‚ a German chemist‚ treated urine to a series of processes that resulted in the production of the element phosphorus. Over the next 200 years

The Development of the Periodic Table Although Dmitri Mendeleev is often considered the ‘father’ of the periodic table‚ the work of many scientists contributed to its present form. Between 1817-1829‚ Johann Dobereiner began to group elements with similar properties in to groups of three or triads. This began when he noticed that the atomic weights of strontium (Sr) were halfway between Calcium (Ca) and Barium (Ba). He stated that nature contained triads of elements in which the middle element
