Experiments with the Tree of Diana have inspired modern chemists to replicate its creation, using the process to analyze reactions between metals and other substances. A 1967 experiment at the University of Seattle studied the reaction between solid copper and aqueous silver nitrate. In it, silver ions reacted with the copper metal to form a ...
Small symbols pack in additional information: solid/liquid/gas, the color of an element, common in the human body, common in the earth's crust, magnetic metals, noble metals, radioactive, and rare or never found in nature. It does not overload kids with a lot of detailed numbers, like atomic weights and valence numbers.
Some metal leaves may look like gold leaf but do not contain any real gold. This type of metal leaf is often referred to as imitation leaf. [3] Metal leaves are usually made of gold (including many alloys), silver, copper, aluminium, brass (sometimes called "Dutch metal" typically 85% Copper and 15% zinc) or palladium, as well as platinum.
The experiment uses a conductive metal container A open at the top, insulated from the ground. Faraday employed a 7 in. diameter by 10.5 in. tall pewter pail on a wooden stool,(B) [ 1 ] but modern demonstrations often use a hollow metal sphere with a hole in the top, [ 10 ] or a cylinder of metal screen, [ 9 ] [ 12 ] mounted on an insulating stand.
A chemical element, often simply called an element, is a type of atom which has a specific number of protons in its atomic nucleus (i.e., a specific atomic number, or Z). [ 1 ] The definitive visualisation of all 118 elements is the periodic table of the elements , whose history along the principles of the periodic law was one of the founding ...

The periodic table, also known as the periodic table of the elements, is an ordered arrangement of the chemical elements into rows ("periods") and columns ("groups"). It is an icon of chemistry and is widely used in physics and other sciences.
Publishers Weekly said that the book was a "lively introduction to the chart that has been the bane of many a chemistry student", [5] and in a review in New Scientist, Vivienne Greig called The Periodic Table "an engrossing read and an ideal way to painlessly impart a great deal of science history to seen-it-all-before teenagers."
