First group belongs to Alkali metals.It consist of lithium,sodium,potassium,rubidium and caesium.They are highly reactive in nature.
There is a group of elements in the periodic table as the elements with same properties are clubbed together.
alkali metals
Yes, there were elements on the first periodic table. I believe that there are still elements on the periodic table.
Gallium is in group 13 of the periodic table. The other elements in this group are Boron, Aluminum, Indium, and Thallium.
Yes it is a group is a family remember that when dealing with the periodic table.
A group in the periodic table is a column of elements that share similar chemical properties due to having the same number of electrons in their outer energy level. Groups are vertical columns and are numbered from 1 to 18.
On the left of the periodic table, especially group 1 and group 2 elements.
All groups in the periodic table contain chemical elements.
2 elements
Periodic table consists of elements not cations. However group 1 and group 2 elements (left side of the periodic table) are elements which will form cations easily.
The first family (Group 1) are the alkali metals.
CO3 is not placed in periodic table. Only elements are arranged in periodic table.
