What are elements in group 1a to 8a called?
Sometimes these are called the "representative" elements.
What are the elements in groups 1A to 8A called?
The elements in group 1a to 8a called representative elements. This is due to the fact that they portray as wide array of chemical and physical properties.
Why are the elements in groups 1A-8A called the representative elements?
They follow a pattern for valence electrons.
How many elements have electrons at ns2np6?
All of the elements in group 8A have this electron configuration except for He! (So a total of 5 elements)
Why are group 8A elements not represented by ionic radius?
they will become another element if they loose or gain 8 electrons
What elements are very stable and have low reactivity?
They are called noble gases or inert elements. Belong to group 8A or 18 They are called noble gases or inert elements. Belong to group 8A or 18 They are called noble gases or inert elements. Belong to group 8A or 18
What are elements in group 1a to 8a called?

Why are the elements in groups 1A-8A called the representative elements?
They follow a pattern for valence electrons.
What is the number of valence electron for the elements in Group 8A?
Eight, except for helium which has two.
What group does the alkaline earth metals belong to?
The alkaline earth metals belong to group 2A elements. The alkali metals belong to group 1A elements. The halogens belong to group 7A elements. The noble gases belong to group 8A elements.
What is group 8A called on the periodic table?
noble gases
