While seaborg was in charge of the group, the group discovered the following elements: plutonium (Pu), Americium (Am), curium (Cm), Berkelium (Bk), and Californium (Cf). While those are the elements that the group discovered while Seaborg was the head, in total, the group discovered all of the elements from #94-#103.
The two elements are berlisium (bm) methonium (meth).
Main group elements have elements from groups 1 and 2, except hydrogen and groups 13 to 18. Main group elements are elements in groups who's lightest elements are shown by helium, lithium, boron, beryllium, carbon, nitrogen, oxygen, and fluorine.
The first periodic table was a handwritten table by Mendeleev. It had groups horizontally across the top and periods down the left hand side. The elements were all put into certain groups with only their chemicals symbols and atomic numbers depicted.
There are 18 groups in the periodic table of elements.
There are 18 main groups in the modern periodic table of elements.
It is similar because you are putting rocks into groups like you are putting elements into groups
On standard ones, Their Symbols, atomic & mass numbers, and groups.
Have a look at the periodic table page on wikipedia. I cannot make out the numbers of the groups.
Elements located in groups 4 - 12 in the modern periodic table are considered as transition elements. Transition elements should not be confused with the d-block elements which are from groups 3 - 12.
because they have similar properties to the other elements in their groups
The groups of symbols are called "formulas" (Latin formulae) because they show the symbols of the elements and ions that are in a molecule of a compound.Example: CO2 (carbon dioxide) contains one atom of carbon and two of oxygen.
s block elements: groups 1-2 d block elements: groups 3-12 p block elements: groups 13-18

Excepting beryllium, the others mentioned elements produce basic solutions when are dissolved in water.
