a none of them
b every eighth elements
c all of them
d half of them
The Representative elements is the answer, or the A family in the olden times
Helium, Neon, Argon, Krypton, Xenon, RadonType your answer here...
The elements of the periodic law are calcium, barium, cesium, and plumbed since there are still more elements out there somewhere those are the more up to date ones.
They are usually grouped in categories besides metals and nonmetals.
You think probable to noble gases. You question is so clear.
Elements with same chemical properties are grouped together. Hence they are closely associated.

You think probable to groups.
Half
The elements phosphorus and sulfur are elements 15 and 16 on the periodic table. They will have more in common than sodium, element 11 and an Alkali metal from Group 1 of the table, will have with either phosphorus or sulfur.
Generally the most reactive elements in the periodic table are found in the first two (left-most) columns: the alkali metal and alkali earths.
All of the elements in column 18 of the periodic table are noble gases. This means their outer electron shells are completely full and in most cases are inert.
The first cloumn in the periodic table has the most reactive elements. The elements decrease in reactivity as you go across the table. in other words alkali metals
Each element has similar properties to the other elements in its group on the periodic table. Sodium is an alkali metal, and those are the elements in Group 1 of the periodic table of elements. We know that lithium, sodium, potassium, rubidium, cesium and francium all have similar chemical properties.
sulfur
Most of the elements on the periodic table are metals.
In the periodic table, the elements are grouped according to their properties. Elements in a group has an equal number of valence electrons. So the elements in a group have most common chemical properties.
The most corrosive elements on the Periodic Table are all of the halogens.

Elements of the periodic table
the vertical column is called group in the periodic table.
118 elements are in the periodic table of elements; some of them are still unnamed (January 2013).
Most of them are metals.
One of the halogenss, chlorine, bromine, iodine

no. all elements discovered (and proposed) are included in the periodic table
