If we still had the modern day model of the Periodic Table, the elements wouldn't be arranged by metals, metalloids, or nonmetals, they wouldn't be in the same families, and periods, and they would just be scattered abroad the Periodic Table. Not a great situation. LOL! :D
The periodic table in chemistry is an arrangement that is in tabular form for all the chemical elements. The elements are organized based on their electron configuration, atomic numbers and so on.
do you mean the why is the average atomic mass not a whole number? because if that is your question, then the answer is that each element has multipal isotopes and the mass you see on the periodic table is the average of all the isotopes together. So there has to be a decimal on the periodic table of elements
It is about the atomic number. the number of protons.
Why are atomic masses of elements not generally whole numbers? The atomic masses listed on the periodic table are a weighted AVERAGE of an element'sisotopes. ... An element's atomic number is the number of protons in its nucleus. Number of protons specifies atom type.

Some common questions about the periodic table include: What is the periodic table? How is it organized? What do the numbers and letters on the table represent? Why are some elements grouped together? How many elements are there in total?
The Periodic Table is.
Elements also possess isotopes. So their average atomic mass is rarely whole number.
Elements are organized in the periodic table by their atomic number, which represents the number of protons in the nucleus of an atom. The atomic number determines the unique properties of each element, and elements with similar properties are grouped together in columns called groups.

Periodic Table of elements.
the elements in the modern periodic table are arrange in the increasing order of their atomic numbers.
After atomic numbers Henry Moseley supported the arrangement of periodic table of Mendeleev after atomic numbers and properties by a strong physical conception: study of the lines of X-ray spectra of chemical elements. It is a true relation between atomic numbers of elements and the wavelenghts of the characteristic X-ray lines.
In the modern form of periodic table, all elements are arranged in increasing order of their atomic numbers. The periodic properties of elements are functions of their atomic weights.
