1) Elements can be classified by their state at room temperature; by whether they exist in nature; and by whether they are metals, nonmetals, or metalloids.
Sounds like the Periodic Table of the elements.
The arrangement of all known elements in order of their atomic numbers is called the periodic table of elements. The periodic table organizes elements based on increasing atomic number, showing similarities in properties and periodic trends across rows and columns.
The vertical columns on the periodic table are called groups. The table is arranged in such a way that all elements in the same group are similar and have the same number of valence electrons.
The purpose is to organize the elements into similar categories to organize the elements in a very structured mannor.. for example, they are arranged by atomic mass, and you can also tell the number of protons, neutrons, and electrons in an element. From this you can also determine the molecular weight, and convert from grams to mols. The periodic table is organized in columns and rows, the columns can tell you what the charge on a particular ion is, and also the number of valence electrons. These are just a few ways the periodic table is arranged, there are many, maaany ways.
The alternative periodic table, such as the Janet or Left-Step periodic tables, may have unique features like organizing elements based on electron configurations or emphasizing the relationships between elements in different ways compared to the traditional periodic table.
Mendeleev arranged the elements in a table in the increasing order of atomic masses and repeating periodic properties. In the modern long-form of periodic table, the elements are arranged in the increasing order of atomic number and repeating periodic properties.

Many more elements are known today then when Mendeleev laid out his table. In addition, he arranged his table by atomic mass and there are places in the periodic table where mass does not always increase. An example is between tellurium and iodine.
The vertical columns on the periodic table are called groups. The table is arranged in such a way that all elements in the same group are similar and have the same number of valence electrons.
The periodic table is just a way of grouping elements according to their atomic numbers. It helps scientists to understand why different elements react in different ways.
The periodic table is arranged by atomic number, which increases from left to right and top to bottom. Elements are grouped together based on similar chemical properties, and are organized into periods (rows) and groups (columns) to show trends in physical and chemical properties.

By atomic number: Elements are arranged in order of increasing atomic number, which is the number of protons in the nucleus. By chemical properties: Elements in the same column (group) typically have similar chemical properties. By electron configuration: Elements are organized based on the arrangement of electrons in their atoms. By periods (rows): Elements are grouped into rows based on the number of electron shells. By blocks: Elements are classified into s-block, p-block, d-block, and f-block based on the type of subshell being filled with electrons.
