How many groups make up the representative elements?
The representative elements occur in groups 1, 2, and 12–18. These elements are representative metals, metalloids, and nonmetals.
Which of the following would not be included in the representative elements?
The representative elements are elements where the s and p orbitals are filling. The transition elements are elements where the d orbitals (groups 3–11 on the periodic table) are filling. among the following Tantalum (Z=73) is not a representative element it is a transition element.

What are representative elements give their general configuration?
The elements of s-block and p-block except noble gases are called representative elements. The general configuration of s-block elements is ns1−ns2. And for p-block elements except noble gases is ns2np1−ns2np5. Thus combined for representative elements it is ns1−ns2p5 i.e., option A.
What is another name for representative elements?
Another name for the representative elements are the Group A elements or the main group elements.
What best describes the properties of representative elements?
Which best describes the properties of representative elements? they display a wide range of physical and chemical properties. What property did Mendeleev use to develop and organize his periodic table?
What are representative elements for class 11?
Answer. The Representative Elements are those elements within the first two families (Groups I and II on the far left) and the last six families or groups (on the right) of the Periodic Table. The Transition Metals are the elements in those Groups within the middle of the Table.
