DOUBLE BUBLE MAPS

techniques using double buble maps

 Elemental comparison techniques using double buble maps

1. look for the elements you want to compare

2. look for element specifications and compare them

Gold is a chemical element in the periodic table that has the Au symbol (Latin: 'aurum') and atomic number 79. A transition metal (trivalent and univalent) is soft, shiny, yellow, heavy, "malleable", and "ductile". Gold does not react with other chemicals but is attacked by chlorine, fluorine and aqua regia. This metal is found in many gold nuggets or powders in rocks and in alluvial deposits and one of the coinage metals. The ISO code is XAU. Gold melts in liquid form at a temperature of about 1000 degrees Celsius.

Iron is a chemical element with Fe (from Latin: ferrum) and atomic number 26. It is the metal in the first transition series. [3] It is the most common element on earth based on mass, forming most of the outer and inner core parts of the earth. Iron is the fourth largest element of the earth's crust. Its abundance in rocky planets like the earth due to the abundance of production due to fusion reactions in massive stars, where the production of nickel-56 (decaying into the most common iron isotope) is the last exothermic nuclear fusion reaction. As a result, radioactive nickel was the last element produced before the supernova great collapse. The collapse scattered iron radionuclide precursors into the sky.

3. Write points of equations and differences

4. Create a diagram like the following

 

5. finish :)
