What are the representative element groups?
The representative elements occur in groups 1, 2, and 12–18. These elements are representative metals, metalloids, and nonmetals.
Where are the representative main group elements?
The main group elements are groups 1, 2, and 13-18 on the periodic table. The main group elements are the chemical elements belonging to the s-block and p-block on the periodic table. These are elements in group 1 and group 2 (s-block) and groups 13 through 18 (p-block).
Why are the main group elements called the representative elements?
Significance of the Main Group Elements The main group elements, along with a few light transition metals, are the most abundant elements in the universe, solar system, and on Earth. For this reason, main group elements are sometimes known as representative elements.
What is main group elements in the periodic table?
The main group elements are classified as belonging to the s- and p-blocks in the periodic table. They range from gases such as fluorine and oxygen through nonmetals (e.g., boron, phosphorus, and sulfur) and semimetals (metalloids; e.g., germanium) to very reactive metals such as sodium and potassium.
What are representative elements examples?

How do you identify representative elements?
Answer: The 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 are known as representative elements. S-lock and P-block elements come under the category of representative elements.
Which of the following is a representative elements?
In chemistry and atomic physics, the main group is the group of elements (sometimes called the representative elements) whose lightest members are represented by helium, lithium, beryllium, boron, carbon, nitrogen, oxygen, and fluorine as arranged in the periodic table of the elements.
What is meaning of representative elements?
The 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 are known as representative elements.
What are representative elements for class 11?
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.
Is Ka main group element?
Group 1 (Alkali Metals) The series consists of the elements lithium (Li), sodium (Na), potassium (K), rubidium (Rb), caesium (Cs), and francium (Fr).
What are non representative elements?
Non-representative elements include the transition elements, which have valence electrons in the s and d shells, and the lanthanide and actinide series, which have valence electrons in the s and f shells. They have unexpected electron configurations.
What are representative elements in art?
The elements belonging to the s and p blocks of the periodic table are called representative elements. They are also known as normal or main group elements.
