Group 17 elements (Gr. 17 are not metals.) are called halogens (halogen group).
17 is the Halogens, and 18 is the noble, or ''inert'' gases
Rows of the periodic table are called periods.
group
A group is a column in the periodic table of elements.
The 3 major groups are: # Metals - Groups 1-15 and the Inner Transitional Elements # Nonmetals - Groups 1 and 14-18 # Metalloids - Groups 13-17 (Diagonal strip of elements separating the metals from the nonmetals)
Groups are the vertical columns on the periodic table. There are 18 groups on the periodic table.Group 1 = Alkali MetalsGroup 2 = Alkaline Earth MetalsGroups 3-12 = Transition MetalsGroup 17 = HalogensGroup 18 = Noble gasesthe table is used in chemistry to list in order like elements----long time since general chemistry
There is no group 17.
Rows of the periodic table are called periods.
The groups of electrons with 7 valence electrons are groups 7 and 17 on the periodic table.
The most reactive group of non metal is group-17. It is called halogen family.
Groups 13, 14 and 15
