What are elements in group 1a to 8a called?
Sometimes these are called the "representative" elements.
What is the difference between period 4 and 5 on the periodic table?
There are 4 electronic shells in period 4 while there are 5 shells in period 5.Elements of period 4 are smaller in size as compared to elements of period 5.Example of period 4 element is potassium and period 5 element is tin.
Are 3-12 elements on the periodic table of elements representative elements?
Yes. All elements from 1-20 are representative elements as they belong to a representative group (i.e. they aren't a transition metal).
What is the representative element in Period 4 with three valence electrons?
Al

Which periods have the same number of elements?
Period 4 and period 5 of the periodic table have the same number of elements. There are 18 elements in each period. While some elements in period 4 are calcium, iron, and zinc, elements in period 5 are tin, antimony, and iodine.
What is the representative element in period 4 group IVA 14?
Germanium belongs to group IVA or group 14 and period 4
What do you mean by Representative Elements?
The representative elements are located in groups 1A through 7A. They are referred to as representative elements because they display a wide range of physical and chemical properties. Some are metals, some are nonmetals, and some are metalloids. The S and P sub-levels of the highest energy are not filled.
