Representative elements, found in groups 1, 2, and 13-18 of the Periodic Table, are characterized by their diverse properties due to their varying valence electron configurations. Group 1 (alkali metals) are highly reactive, particularly with water, and have one valence electron. Group 2 (alkaline earth metals) are also reactive but less so than alkali metals, with two valence electrons. Groups 13-18 include metals, metalloids, and nonmetals, with properties ranging from the metallic behavior of aluminum (Group 13) to the nonmetallic properties of halogens (Group 17) and noble gases (Group 18), each exhibiting distinct reactivity and bonding characteristics based on their valence electron counts.
elements are grouped together into families as they have simliar properties. all the elements in each collum or period have imilar chamical properties.
Each family of elements has its own set of characteristics that each of the elements possess.
The difference is made by the number of protons, specifi for each element.
The columns represent groups or families of elements. There are 18 of them.
It tells what elements are present in a molecule and how many atoms of each element are present.

The elements in group 1 and 2 are the representative elements. Groups 3 through 12 are the transition elements. Transition elements are all metals and are found less noticably than they do across a period of representative elements. representative elements are always found in nature combined with other elements, they are all metals except for hydrogen.
Each neutral atom has a specific electron cofiguration.
The difference between a district representative and a senator is the pay scale. A senator would get paid more. There is also a difference in the number of constituents for each. A senator represents an entire state, and a district representative only represents a part of the state.

They follow a pattern for valence electrons.
The elements in groups 1A to 8A are called the representative elements or main group elements. Each group corresponds to a specific column on the periodic table and has similar chemical properties due to their electron configurations.
Oh honey, the Representative Elements are just the main group elements on the periodic table. They're the popular kids at the chemistry party, hanging out in groups 1, 2, and 13-18. They're the ones who aren't trying too hard to be cool, just doing their thing and bonding with other elements to form compounds.
