Seaborg actually produced more than two. He produced Plutonium (Pu), Americium (Am), Curium (Cm), Berkelium (Bk) and Califormium) (Cf).
There is a total of 17 elements in those groups.
Group 18 (Noble Gases) contains the largest main group elements because they have the highest atomic numbers and largest atomic radii among the main group elements.
Group 1 Elements (elements in the first group [column]) are classed as Alkali Metals. Group 2 Elements (elements in the second group [column]) are classed as Alkaline Earth Metals. All elements not in a representative group are classed as Transition Metals. Group 3 Elements (elements in the third full group [coulumn]) are classed as Earth Metals
Lithium, Rubidium, Cesium, Francium. Li , Rb , Cs, and Fr
Salt formers / group 17 elements. The elements of Group VII (or group 17) of the Periodic Table are called halogens, which means "salt formers"
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 alchemists were a group of early experimenters who used symbols to identify certain elements, creating a symbolic language to represent various substances and processes in their experiments. These symbols evolved into the modern chemical symbols we use today.

All elements appear in the periodic table, there are more than 100 of them, so please look at the related link below to see an example of such table and all symbols of them.(Please note that there is no special group of 'periodic' elements)
This combination of symbols is known as a chemical formula.
Li, Na, K etc., 1st group elements Ca, Ba etc., 2nd group elements, give the strongest bases
The transition metals often produce colorful compounds.
There is no method to designate such properties. Only symbols with atomic number are mentioned.
Bloch and Trager define language as a system of arbitrary vocal symbols that are used for human communication. They view language as a rule-governed system with a finite set of elements that can be combined to produce an infinite array of meaningful utterances.
Some elements are named after the compound that they came from, or some attribute of it. Other elements are named after some aspect of the way in which the element was found. Still, there are other elements that get their names from places. Another interesting group of names comes from mythology. -Nev Singhota
elements are in the same group since they react similarly to other elements in that group.
