All groups except the lanthanoids and the actinoids.
Groups are columns on the periodic table. Lithium is in the first column on the periodic table. Those elements are called alkali metals and include not only lithium but sodium, potassium and others.
Elements in the same column (group) of the periodic table have similar chemical properties because they have the same number of valence electrons. This results in them having similar reactivity and forming similar types of bonds with other elements.
The halogens are the highly reactive nonmetals on the periodic table. This group includes elements such as fluorine, chlorine, bromine, and iodine, which readily form compounds with other elements due to their strong tendency to gain an electron.
The y are orgnized by there atomic number and if you need more answers dont use wikipedia.com they dont have right answers and anyone can change the answers as they please so use a diffren site if you want a good grade on anything
The column next to the noble gases in the periodic table is the halogens group. Halogens are highly reactive because they only need one more electron to complete their outer electron shell and achieve a stable electron configuration. This makes them eager to chemically react with other elements to gain that electron and become stable.
No. The noble gasses take up a single column of the periodic table
They have similar (more or less) chemical properties.
There is no group named 'you' in the periodic table.the groups in the periodic table are numbered, and have names that identify the general class of elements in that group, e.g. 'halogens'.See this question/answer for more details: What_are_the_group_names_in_the_periodic_table
The elements called lanthanoids and actinoids.
In the same column (group) but in a row below the chemical you start with.
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.
Alkali metals: Group 1 in the periodic table Alkaline earth metals: Group 2 Halogens: Group 17 Noble Gases: Group 18 You can easily find them if you look at a periodic table.

Less.
Elements in the same column (group) of the periodic table have similar chemical properties because they have the same number of valence electrons. This results in them having similar reactivity and forming similar types of bonds with other elements.
They lose it
Group 1 elements are more reactive than that of group 2 elements.
