Writing for Hobby and Leisure Activity Magazines

Writing for Hob When I began my freelance writing career in 2007, I would never have believed Id end up writing dozens of articles for hob My Ive found hob Leisure activity magazines exist in a mind-boggling plethora of topics; trains, quilting, motorcycles, automobiles, cats and dogs, dolls, scale modeling, yachting, cycling, running (and nearly every other sport imaginable), camping, hiking, video games, arts crafts, astronomy, military history, stamp collecting, coin collecting, rock gem collecting, antique collecting, and every other pastime imaginable. Next time youre at your local Barnes Noble or bookstore, thumb through the special interest and hob Where to Pitch Your Hob Leisure activities represent a huge market in first world countries. So, make sure you pitch your stories to magazines published in developed countries that have wealth and where the people have leisure time for pursuing hobbies such as North America, the U.K, Australia, New Zealand, South Africa. You Dont Have to Be an Expert Writers do not need to be experts about their hob Ive consulted or quoted experts in some hob My article in Garden Answers Magazine, about the Elandan Bonsai Gardens in Port Orchard, Washington, was a profile piece about Daniel Robinson, a bonsai expert who created this magical garden. How Do You Pitch Your Story Ideas to Hob Hob Create Pitch Lists Ive created extensive magazine distribution lists for every leisure activity genre that Ive written in. Once youve developed your magazine distribution lists, youve got them forever, so you dont need to reinvent the wheel every time you want to query a hob Writing for hob

Radon Chemical and Physical Properties

Radon Chemical and Physical Properties Atomic Number: 86 Symbol: Rn Atomic Weight: 222.0176 Discovery: Fredrich Ernst Dorn 1898 or 1900 (Germany), discovered the element and called it radium emanation. Ramsay and Gray isolated the element in 1908 and named it niton. Electron Configuration: [Xe] 4f14 5d10 6s2 6p6 Word Origin: from radium. Radon was once called niton, from the Latin word nitens, which means shining Isotopes: At least 34 isotopes of radon are known ranging from Rn-195 to Rn-228. There are no stable isotopes of radon. The isotope radon-222 is the most stable isotope and called thoron and emanates naturally from thorium. Thoron is an alpha-emitter with a half-life of 3.8232 days. Radon-219 is called actinon and emanates from actinium. It is an alpha-emitter with a half-life of 3.96 sec. Properties: Radon has a melting point of -71Â °C, boiling point of -61.8 Â °C, gas density of 9.73 g/l, specific gravity of the liquid state of 4.4 at -62Â °C, specific gravity of the solid state of 4, usually with a valence of 0 (it does form some compounds, however, such as radon fluoride). Radon is a colorless gas at normal temperatures. It is also the heaviest of the gases. When it is cooled below its freezing point it displays a brilliant phosphorescence. The phosphorescence is yellow as the temperature is lowered, becoming orange-red at the temperature of liquid air. Inhalation of radon presents a health risk. Radon build-up is a health consideration when working with radium, thorium, or actinium. It is also a potential issue in uranium mines. Sources: It is estimated that each square mile of soil to a depth of 6 inches contains approximately 1 g of radium, which releases radon to the atmosphere. The average concentration of radon is about 1 sextillion parts of air. Radon naturally occurs in some spring waters. Element Classification: Inert Gas Physical Data Density (g/cc): 4.4 ( -62Â °C) Melting Point (K): 202 Boiling Point (K): 211.4 Appearance: heavy radioactive gas Specific Heat (20Â °C J/g mol): 0.094 Evaporation Heat (kJ/mol): 18.1 First Ionizing Energy (kJ/mol): 1036.5 Lattice Structure: Face-Centered Cubic CAS Registry Number: 10043-92-2 Trivia Ernest Rutherford is sometimes credited with the discovery of radon. He actually discovered the alpha particle radiation given off by radon.Radon became the official name for element 86 in 1923. The IUPAC chose radon from the names radon (Rn), thoron (Tn) and actinon (An). The other two names are given to isotopes of radon. Thoron is Rn-220 and actinon became Rn-219.Other suggested names for radon included radium emanation, niton, extadio, exthorio, exactinio, akton, radeon, thoreon and actineon.The U.S. Environmental Protection Agency lists radon as the second highest cause of lung cancer.
