Is the Periodic Table still useful in its current form or does it need to change?
The Periodic table is set up in a particular way by scientists with most being done over 100 years ago.
Is that set-up still useful and meaningful to today's students who have to use it to interpret chemistry? Can we still claim that the Periodic Table talks a universal language and there is a finite number of elements that could possibly exist?

This modern periodic table setup is more useful than a periodic table from 100 years ago because the layout of the elements (Periods and groups) make is very easy for students to find out information about the certain element. Such as to find the trend going across each row and the number of shells each element has, we can use the periods (horizontal) to give us the information. While finding the number of valence electrons can be by reading the groups (vertical) to tell us. The groups is are split up by what type of element it is (Group 1 is alkali metals, group 2 is alkaline earth metals...) The scientists can use the modern layout of a periodic table to identify basic facts and use those facts to discover something more advanced. In addition, different versions of and how it's arranged serves scientists in different fields
ReplyDeleteDo you think there are any more elements to be discovered? Why do you think we have not discovered them yet?
DeleteThe modern period table and this periodic table is =both meaningful to today’s as it is arranged according to the atomic number is the most fundamental property of an element and not its atomic mass. However chemists would choose to use the modern periodic table over this one because the modern periodic table organises the periods and groups in rows and columns allowing chemists to be able to easily refer to the table as the properties vary gradually from one element to the next. We can still claim that the periodic table talks a universal language as scientists of different fields of work can refer to the table to help them predict and identify chemical reactions from knowing an elements general properties.
ReplyDeleteYes, although the set up was established in the past and was a bit outdated, I believe that the set up is still useful and meaningful to today's students. We should build on the set up and modify the set up with what we newly discover and make it fits today's use. We can still claim that the Periodic Table talks a universal language as it covers most of the elements in the world. Lastly, I think that there is a finite number of elements that could possibly exist but I believe that there are still elements, which are not listed in the Periodic Table, that are yet to be discovered.
ReplyDeleteAn interesting thought. Why do you think there are more to be discovered? Why haven't they been discovered yet?
