Visualize trends, 3D orbitals, isotopes, and mix compounds. Such chemistry also explains why mercury metal is a liquid at room temperature, despite periodic table predictions. The mercury dissolved the gold which could be reclaimed by distilling off the mercury. You do not have JavaScript enabled. Members of a group typically have similar properties and electron configurations in their outer shell. Hydrogen is a chemical element with atomic number 1 which means there are 1 protons and 1 electrons in the atomic structure.The chemical symbol for Hydrogen is H. With a standard atomic weight of circa 1.008, hydrogen is the lightest element on the periodic table. This number is the atomic number. Chemistry in its element is brought to you by the Royal Society of Chemistry and produced by. Mercury was used in many experiments to transmute one metal into another. We hope that you enjoy your visit to this Site. Each element is identified by the number of protons in its atoms. How to Memorise the Periodic Table. Interactive periodic table showing names, electrons, and oxidation states. Half of the distance between two atoms within a single covalent bond. The temperature at which the solid–liquid phase change occurs. Mercury is a chemical element with the symbol Hg and atomic number 80. Images © Murray Robertson 1999-2011 Mercury is used to make thermometers, diffusion pumps, barometers, mercury vapor lamps, mercury switches, pesticides, batteries, dental preparations, antifouling paints, pigments, and catalysts. Mercuric sulfide (vermilion) is a high-grade, bright-red paint pigment, but is very toxic so is now only used with great care. On one hand, it saddens me to think that mercury will eventually be an elemental artefact sitting hopelessly between gold and thallium in the periodic table, but on the other, it constantly reminds me of the dangers that hide behind the façade of its beautiful silver lustre. The sum of the oxidation states within a compound or ion must equal the overall charge. Metals, nonmetals, and metalloids make up the periodic table, with metals constituting the large majority of all metals. The percentage of an element produced in the top producing country. These blocks are named for the characteristic spectra they produce: sharp (s), principal (p), diffuse (d), and fundamental (f). There are 166 periodic table sign for sale on Etsy, and they cost £26.69 on average. A measure of how difficult it is to compress a substance. The availability of suitable substitutes for a given commodity. The dragon or serpent in the background comes from early alchemical drawings and is often associated with the element. China and Kyrgyzstan are the main producers of mercury. Text © The Royal Society of Chemistry 1999-2011 The number of protons in an atom. It is given by the ratio of the shear stress to the shear strain. It is defined as being the charge that an atom would have if all bonds were ionic.

Don't ask me how the conversation had reached this point, but being surrounded by friends, who would, it is fair to say, describe themselves as science illiterate, I knew it was up to me, the token scientist around the table, to give the definitive answer.
