Doubt On Periodic table

Question asked by Sai Tanishq Nannapaneni on Apr 22, 2016

Hi ACS chemists. I have doubt on periodic table especially on arrangment of radio active elements and the elements of the 7th period dont have the same properties as that to which group they belong to and the new elements are possible in near future so where we gone place the elements and a new period (i.e8th)should be formed if that is the case then table becomes lenghty. Is there any alternative i mean we have to palce these radioactive elements in seperate table from the periodic table.If so i have a design ...if u find any find any mistake in my above theroy can please reply me.If u reply me there is no such amistake i would send my design to you.
