Verified step by step guidance1
Understand that the periodic table is divided into blocks based on the electron configuration of the elements: s-block, p-block, d-block, and f-block.
Recognize that representative elements, also known as main-group elements, are those in which the outermost electrons are in the s or p orbitals.
Identify that the s-block includes groups 1 and 2, which contain the alkali and alkaline earth metals respectively.
Identify that the p-block includes groups 13 through 18, which contain elements such as the boron group, carbon group, nitrogen group, oxygen group, halogens, and noble gases.
Conclude that the representative elements are located in groups 1, 2, and 13 through 18 on the periodic table.
