Stunning crystal chemical hypnotic photos
If you remember In the periodic table of elements, if you react with heat in the kitchen, Zhu Wenting and Yan Liang are here to re-establish your relationship with the elements.
Generate images in 300 photo sets The beauty of chemistryToday, Zhu Heliang uses infrared thermal imaging technology, as well as high-speed and time-lapse macro photography, to bring readers into the tiny world of molecules and the often amazing reactions between them. The scientific writer Philip Ball has the clarity of the atom. He describes this visual journey through the under-recognized chemical beauty around us, from describing the principle of the unique symmetry of snowflakes to the combination of silicate The resulting realistic tendrils are related to life itself, which is clear at a glance.
Perhaps the most basic and surprising of these concepts is the hydrogen bond, which holds the real things in life together: water. Each water molecule consists of two hydrogen atoms bonded to oxygen atoms, but oxygen has six electrons in its shell. Only two electrons are needed to form a chemical bond with hydrogen, so four negatively charged electrons (grouped in pairs in “hanging” pairs) are hovering in the microspace to find a way to balance themselves. These pairs faintly pull on the hydrogen atom that is bonded to the adjacent water molecule, forming a short tenth of a second bond, then breaking and reforming with another hydrogen atom. It is this constant dance that makes the chemical movement possible to make life, which Bauer calls “molecular dialogue”, hovering between order and chaos.
The chromium hydroxide precipitate is in the process of solidification while rotating and diluting in its container. This reaction occurs when two liquid compounds containing both positively and negatively charged ions gather together and form a molecular scroll, in which case they become trading partners. In this case, chromium chloride and sodium hydroxide will exchange ions. The positively charged chromium and the negatively charged hydroxide molecules attract each other because they are energetically balanced. They form tight bonds, freezing the molecules in place, forming a solid by-product, which does not have room for all the water molecules to be neatly contained. This reaction also produces sodium chloride, commonly called table salt, which happens to be soluble in water.
