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.
Elements are usually classified as metals, non-metals, or metalloids.

It's number, the element type, and also the what type of substance it is. There is usually a key near the bottom or top of a Periodic Table.

Sounds like the Periodic Table of the elements.
The list is often called the periodic table, given that it can be arranged in ways which bring out the patterns in their reactivities.
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 periodic table reflects real and useful ways to categorize the elements according to some basic characteristics within groups.
It wasn't necessary, but it was very helpful. By arranging the elements in a periodic table, it makes it much easier to see patterns and trends in the properties of the elements. For instance, all of the elements in each column of the periodic table have similar properties because their electron configurations are related. Using the periodic table, you can predict with fairly good accuracy the properties of an element you've never even seen just based on where it is in the periodic table. It is a very powerful tool for chemists.
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 periodic table is arranged (1) by increasing atomic number; (2) into groups of elements with similar chemical properties; (3) into periods of elements with the same number of electron shells.

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 organized in several ways: 1) They are organized according to increasing atomic number, which usually does coincide with increasing atomic mass. So, if you look at the periodic table from left to right, or top to bottom, you will notice that the atomic numbers become larger. 2) The periodic table is organized horizontally into rows which are called "periods." Each element from left to right in a period gains a proton. So, in the first period, H has one proton, and He has two protons. 3) Now, the periodic table is also arranged into a system vertically as well. These vertical rows are called "groups," and are arranged according to their chemical characteristics and properties. These groups are denoted by A or B, group A being representative elements, and group B being transition metals. Those are three ways that the periodic table is organized. Furthermore, the periodic table also categorizes the elements into 3 groups: metals, metalloids and non-metals.
Every day, you drink water. (Hydrogen, Oxygen) You eat salt. (Sodium, Chlorine) You breath air. (Oxygen) You eat sugar. (Carbon, Hydrogen, Oxygen) You brush your teeth. (there is baking soda in toothpaste, baking soda is made of Sodium, Hydrogen, Carbon, Oxygen) --PainRain
He formulated the Periodic Law and revised and predicted the Periodic Table of Elements in some important ways.
