The Periodic Table This modern periodic table lists elements according to their atomic number, if they were arranged according to atomic mass potassium and argon would be the wrong way round Elements having the same number of electrons in their outermost shell are placed in vertical columns called groups They have similar chemical propertiesPearson's Edexcel International GCSE Chemistry books The Periodic Table Online Periodic Tables WebElements Masses of useful information about the elements and their simple compounds The only downside is its obtrusive advertisements Fast Periodic Table From wwwschoolsciencecouk (produced by the UK Association for Science Education)There are more than 100 different elements The periodic table is a chart showing all the elements arranged in order of increasing atomic number The vertical columns in the periodic table are
Elements are arranged on the Periodic Table in order of increasing atomic number, where each element has one proton more than the element preceding it The table is arranged in vertical columns called Groups numbered 1 – 8 and in rows called Periods Period these are the horizontal rows that show the number of shells of electrons an atom hasSilicon 14 2,8,4 Phosphorus 15 2,8,5 Sulfur 16 2,8,6 Chlorine 17 2,8,7 Argon 18 2,8,8 Potassium 19 2,8,8,1 Calcium 2,8,8,2 Note although the third shell can hold up to 18 electrons, the filling of the shells follows a more complicated pattern after potassium and calcium For these two elements, the third shell holds 8 and theFor Students Your Profile;

Learn who made the periodic table, why he arranged the elements this way and about the important groups you need to knowChemistry The Periodic Table (AQA) A basic understanding of the fundamental ideas in chemistry is required of students in GCSE Science This is the second of six quizzes going over these fundamental ideas and it looks specifically at the periodic table The periodic table is a fundamental part of chemistry and we take it and its usefulness for granted, but that hasn't always been theThe periodic table below is based on the ones used by the different examination boards The group numbers 1 to 0 (the top ones) are used in most GCSE courses The group numbers 1 to 18 were recommended by IUPAC in 19 At the moment these are only used in OCR courses There is a summary at the bottom of the page It shows the differences

The Periodic Table In 1869 a Russian scientist called Dimitri Mendeleev published his Periodic Table which arranged the elements to show patterns in their chemical properties With just a few adjustments the modern Periodic Table was produced and became one of the most important tools in chemistryOr Having some additional hours of tuition with an experienced chemistry teacherThe elements in group 0 are called the noble gases They belong to the righthand column in the periodic table The noble gases are all chemically unreactive which means they are inert noble gases He helium, Ne neon, Ar argon, Kr krypton, Xe xenon, Rn radon;
