How Periodic Table Has Changed Over Time
HOW THE PERIODIC TABLE OF ELEMENTS HAS CHANGED OVER TIME?
The periodic table has changed a lot since the first one was created, it has also expanded and has more elements it has also changed the weight of other elements., it was first created in rows and columns and all different confusing symbols and equations, the periodic table today is a lot more structure and easier to understand. The periodic table has is always being changed s new discoveries are being made and new theories are being developed to explain the behaviour of chemicals.
The periodic table was created in 1869 by Dmtrri Mendleev, it was small and not set out well, only have a handful of element of the table, he arranged the elements known at the time in order of relative …show more content…
The periodic table has been around for almost 140 years and has gone through many revolutionary discovery’s including that of subatomic structure and development of quantum physics and mechanics and relativity. The order of elements was originally done by their increasing atomic weight it was found later that atomic number provided a better ordering tactic. For example, the elements tellurium and iodine fell perfectly into place according to their chemical behaviour, but their position on the table would have been inverted if put in order by their atomic …show more content…
A source has said “I was always taught the periodic table of elements in school as a kid and I never got the hang of it or remembered it, I always struggled”. Chemists believe that if the periodic table of elements could be planned out simpler they would as they believe there is no easier way. However, some people disagree with this as they think there are many was that the periodic table of elements could be arranged in a much easier way so that it would take years and years and practise and revisitation. Some teachers and parents believe that the parodic table of elements is way too hard to tech younger primacy students and needs to be made easier or a new one should be developed to young primary children so that the children have more of a chance to remember the periodic table to their progress though school and adult hood.
The discovery of 118 chemical elements are set out in the chronological order as they are seen today. The elements are listed as which each was first defined as a pure element as the exact date of which the elements were discovered are not all defined. There are plans to synthesise more elements. There have been many findings added to the periodic table of elements from may country’s around the
