The Discoid Periodic table is an alternative layout of the Modern Periodic table.

Discoid Periodic Table on Wikipedia

Discoid Periodic Table on MetaSynthesis

This table instead of having "Groups" and "Periods” possesses "Families" and "Arcs" for the representation of elements. All the elements in the column shall be identified vertically by their Family name by using the top element name. i.e., Lithium Family, Beryllium Family, and so on. Similarly, elements shall be identified horizontally by using the number of arcs. i.e., 1st arc, 2nd arc, etc. The periodic table shall be divided into two parts, namely Part "A” and Part "B”. Part "A" represents the Representative elements, whereas Part "B” represents the Transition metals.

Salient Features: Now, let's list the features of this Periodic table, as it has removed all the defects of the previous table.

• Proper Position of Hydrogen: Hydrogen has always remained a dispute among some Groups as it shares many similarities among them. But it could only be placed in any one of them, so for this reason, it was either placed in Group-I A or as a separate block at the top. But the Discoid Periodic table has solved this long-time issue by placing it at the center of the table, from where it shall share many interstitial chemical properties with other elements of different Families. There is a sense that Hydrogen underlies everything rather than being the first element because the chemical elements are mostly formed via the fusion of H and He

• Placement of "La" and "Ac": The Lanthanide and Actinide series is a series of elements placed outside the Periodic table because they are Radioactive and mostly man-made, moreover they are f-block elements. This huge problem was also got resolved by dividing the table into two portions, which provides plenty of space. Moreover, it doesn't disturb the overall periodicity of the Table.

• Better Position of Helium: Helium also carried some similar problems. Helium is an element of Group-VIII A and shares the same chemical properties as it's a Noble gas itself, but according to the electronic configuration, it's an s-block element but all the other Noble gases are p-block. This issue has been resolved by placing Helium in the 1st arc with Hydrogen, so now it will be in the s-arc and shall be connected with its Group.

• Modification of Group-B: Group-B carries the most defects of all because the Group starts from III B to VIII B, then comes I B and II B. Moreover, Group VIII B occupies three columns rather than one. This defect is solved by Part "B" which has no Groups (or Families) because there is no need for it. All Transition metals are almost chemically and physically the same, with no big difference.

Different, yet the same: The table though in appearance may look something new and extraordinary, but on closer look is the same in terms of Periodicity as only the structure has been changed which eliminated the defects.

Conclusion: In Conclusion, from the above discussion it can be said that this Table, shall remove all the defects which the previous Periodic Table upholds. Furthermore, it shall be viable for a long period of time. This version of the Periodic Table reflects the ongoing scientific endeavor to classify the world around us.

These colorful, fun, and informative periodic tables are great for elementary, middle, and high school students, as well as adults.

So I have mini poster project thing in science class, and I chose to do mine on francium. But there aren't many uses for it and my teacher wants everyone to find at least three uses for the element they chose and with francium I don't think she would mind if I couldn't find 3 uses. But I am wondering what uses there are for francium or at least if there is anything it can be found in. I did research and some sites said it can be used for cancer curing diagnostic, experiments, and in research. But I'm not sure how accurate that is. Can someone help me here?? If you can give an explanation in both French and English that would be appreciated

just joined this group we should get more people to join somehow, but thanks to everyone who is in here

I recently chatted to Dr Kathryn Harkup on my podcast who has recently written a book on 'The Secret Life of Elements', and the conversation turned to 'favourite elements.' As a comedian I did not have one, had not thought of it but since the conversation I am going to say I absolutely love that Mercury seems to be the elemental embodiment of the Punk rock movement, in that it did not conform to any of the rules and so people found a way to make it useful for their own causes (enter the pop punk era of the early 2000s).
The conversation was delightfully odd and nerdy and made me wonder what other people's elements are and why (you can listen to our chat here for context).

What are all the types of compounds that when reacted with water form CO2 or carbonic Acid

The most toxic element is plutonium.
