What did Dmitri Mendeleev discover?
he drew up a table that grouped elements according to their atomic weights, his table became the basis for the periodic table of elements used today.
Where are the representative elements on the periodic table?

The three domain system arose when scientists grouped organisms according to how long they have been?

What does the periodic table show us about atoms of various elements?
Periodic table show that elements have properties which are periodic in nature. These properties can be grouped together.
What is a central or essential part around which other parts are gatherd or grouped?
A central or essential part around which other parts are gathered or grouped is often referred to as a "hub." This hub serves as the focal point that organizes and connects various elements, facilitating interaction and coordination among them. In different contexts, it could refer to a physical location, a concept, or a system that provides structure and coherence to surrounding components.
Are representative elements grouped according too valence electrons?

How are representative elements grouped?
The representative elements, or main group elements, consist of all elements in the table's "s" and "p" blocks, excluding the noble gases. They are grouped into alkali metals, alkaline earth metals and post-transitional metals.
What are the elements in the A columns of the periodic table called?
The elements in the A columns of the periodic table are called representative elements or main group elements. They are grouped into families based on similar chemical properties and valence electron configurations.

How are elements grouped?
they are grouped by the number of valence electrons.
What element is not grouped with other elements?
hydrogen
Are 3-12 elements on the periodic table of elements representative elements?
No, 3-12 elements on the periodic table (group 3 to group 12) are transition metals, not representative elements. Representative elements are found in groups 1 and 2, and 13 to 18 on the periodic table.
