It is because Mendeleev based his Periodic Table on the elements being arranged from lightest to heaviest. It also makes more sense to have the reactivity arranged effectively and metals and nonmetals categorised together.

∙ 13y agoElements with similar electron arrangements (in a column) and numbers (in a row) have similar properties, making electron-number arrangement a useful organization. This arrangement is also the most simple one devised, so simple to understand and find answers.

∙ 13y agoBy arranging the periodic table of elements by atomic number, elements having the same valence form columns, such as the noble gases column (valence zero), the halogen column (valence -1) and so forth. It makes the chemical behavior of the elements much more easily understandable.

∙ 14y agoThat's how the elements are ordered; by atomic number.
Wiki User
∙ 13y agoMost periodic tables display the atomic numbers because they show the progression of atomic weights and increasing number of protons.

∙ 12y agoi's just a coincidence that their atomic numbers go up in ones every time, so they used this coincidence to form the periodic table

How is the periodic table arranged in terms of their ato mic structures?
The elements in the periodic table are arranged in order of increasing atomic numbers.
Is the periodic table is most easily understood in terms of the electron configurations of the elements?
Yes. In terms of electron configuration and the number of valence electrons.
How can you compare and contrast the periodic table that Mendeleev developed to the periodic table that Mosley organized?
Mendeleev used atomic masses to classify the element, where as Moseley classified the element in terms of atomic number, he suggested that chemical and physical properties are the functions of the atomic number Elements in the periodic table is classified as Metals, Nonmetal and Metalloids. Normally Group 1 to 12 are metals... Sayed Abdul Aziem Sayed_abd2007@hotmail.com
What happen to electrical conductivity down the group in a periodic table?
The organization of the periodic table in terms of conductors of electricity could also be said to be the organization of the periodic table in terms of metallic character, since metals are the best conductors of electricity. Metallic character decreases across a period and increases down a group.
Why is fluorine special in terms of elctronegativity?
Flourine is the most electromagnetic element on the periodic table.
How is the periodic table arranged in terms of their ato mic structures?
The elements in the periodic table are arranged in order of increasing atomic numbers.
Is the periodic table is most easily understood in terms of the electron configurations of the elements?
Yes. In terms of electron configuration and the number of valence electrons.
How did mendeleev arrange his version of the periodic table?
Mendeleev arranged his version of the Periodic Table in terms of ascending atomic weights and similar properties. Since it was first published in 1869, there have been updates and improvements.

How are all of the nonmetal elements on the periodic table related terms of ability to lose electrons?
All non-metals have either 5, 6 or 7 electrons in their octet which makes them suitable to gain electrons to achieve stability. Hence it is difficult for electrons to lose electrons.
How are all of the non metals elements on the periodic table related in terms of ability to loose electrons?
Nonmetals are closer to a full outer shell. They would rather gain electrons to complete the shell. They are unlikely to lose electrons.
What terms can be used to describe a horizontal role of a periodic table?
The horizontal rows are called Periods. There are 7 periods in periodic table.
What does periodic mean in science terms?
Usually when saying "periodic," scientists usually refer to the periodic table. This table is the shortened version of gasses, solids, liquids, and so on.
Why do selenium and sulfur have similar chemical properties in terms of electron configuration?
This is because they both have the same amount of valence electrons look on thereferencetable periodic table of elements if your in chemistry.
What is the ''periodic table of elements''?
Scandium.
What terms that refers to the elements to elements in a column of the periodic table?
iDkkk Lmaoo !!
How are elements organized in columns in the periodic table?
Elements are organised in terms of properties in same column. Properties are found to be periodic .
