The Periodic Table The periodic table of the chemical elements (also periodic table of the elements or just the periodic table) is a tabular display of the chemical elements.
Although precursors to this table exist, its invention is generally credited to Russian chemist Dmitri Mendeleev in 1869, who intended the table to illustrate recurring ("periodic") trends in the properties of the elements. The layout of the table has been refined and extended over time, as new elements have been discovered, and new theoretical models have been developed to explain chemical behavior.
The periodic table is now ubiquitous within the academic discipline of chemistry, providing a useful framework to classify, systematize, and compare all of the many different forms of chemical behavior. The layout of the periodic table demonstrates recurring ("periodic") chemical properties. As of 2010, the table contains 118 chemical elements whose discoveries have been confirmed. 15 Awesome Chemistry Experiments. You don’t need to watch Breaking Bad to know that chemistry is pretty awesome.
Below we explore our favorite 15 chemistry GIFs. Melting Metal With Magnets The Science: The copper wire has a significant amount of AC electricity running through it, causing it to act like a really strong electromagnet. In the metal slug, eddy currents form due to the magnetic field the copper wire is causing while the copper wire has high frequency AC flowing through it. The metal slug’s electric resistance causes a portion of the electric energy to turn into heat, but the heat builds up until the metal slug becomes white hot and melts. Orange LED Light In Liquid Nitrogen The Science: When an LED is immersed in liquid nitrogen, the electrons lose a lot of thermal energy, even when the light isn’t turned on.
Heating Mercury Thiocyanate The Science: It is an inorganic chemical compound, the salt of Hg2+ and the thiocyanate anion. Hydrogen Peroxide Catalyzed by Potassium Iodide Burning Magnesium In Dry Ice. So sehen Atome aus! From the Lab: Breaking Bad, Chemistry Good « ScriptPhD. I must preface this next post with a little truth in advertising. I’m a chemist. True blue, to my very core. College degree in physical chemistry, PhD in chemistry. So when I heard about a cable show on AMC whose whole premise rested on a chemistry teacher manufacturing meth, I must say, I was slightly skeptical. ScriptPhD Grade: A+ The Premise If the pilot episode doesn’t get your attention in the first five minutes, then I don’t know what will. In addition to Walt (played by the talented Bryan Cranston), and Jesse (dazzling newcomer Aaron Paul), we meet Skyler (Anna Gunn), Walt’s supportive but perplexed wife, who grows to be very suspicious of him as he has a harder time curtailing his clandestine activities, and Walt, Jr., a teenager with Cerebral Palsy, sensitively portrayed by RJ Mitte.
The Science Science on Breaking Bad is given the red carpet treatment: it’s sleek, sexy, geek-chic, tongue-in-cheek and everywhere. Chemical makeup of a simple voltaic electrochemical cell. Kaboom!
