Grill Cover with Periodic Table Cook Elements
Grill Cover Made From Commercial Quality Marine Grade Vinyl
The Periodic Table of Elements has the ability to spell out many words. Two of these words are Cook and Bacon and it goes right on the front of your Grill Cover! Cant get any better than grilling Bacon and having your grill cover announce it to the world.
The Periodic table of elements has a long, rich history. In 1669, Hennig Brand, an amateur alchemist, attempted to create a Philosopher's Stone. He was the first to discover phosphorous by heating up residues in boiled urine while a liquid dropped out burst into flames. In 1680, Robert Boyle discovered phosphorous as well and made it public. In 1809 47 Elements were discovered and scientists began to see patterns in the characteristics of these elements. In 1863 John Newlands divided the then 56 elements in 11 groups based on their characteristics. In 1869 Dimitri Mendeleev started the development of the periodic table. He arranged the chemical elements based on their atomic mass. He predicted the discovery of other elements and left spaces open for them on the periodic table. In 1886 Antoine Bequerel first discovered radioactivity. A student from New Zealand, Ernest Rutherford, named 3 types of radiation, Alpha, Beta, and Gamma rays. Marie and Pierre Curie started working on Uranium and thorium, and subsequently discovered radium and polonium. Their major discovery was beta particles were negatively charged. The Noble Gases were discovered in 1894 by Sir William Ramsay and Lord Rayleigh. The Noble Gases were added to the periodic table as group 0. In 1897 English Physicist J.J. Thomson first discovered electrons. These were negatively charged particles in an atom. Their exact charge and mass were determined by John Townsend and Robert Millikan. In 1900 Bequerel discovered that electrons and beta particles are the same thing. Rutherford, in 1903, announced that radioactivity is caused by the breakdown of atoms. In 1911, Rutherford and Hans Geiger discovered that electrons orbit the nucleus of the atom. In 1913 Bohr discovered how electrons move around a nucleus in discrete energy called orbitals. Radiation is emitted during movement from one orbital to the next. In 1914, Rutherford first identifies protons in the atomic nucleus. In 1932 James Chadwick first discovered neutrons, and isotopes were identified. This was the complete basis for the periodic table. In 1945 Glenn Seaborg identified lanthanides and actinides which were usually placed below the periodic table.
