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
Yes, the farther right and down you go, the heavier the element
Revised answer: If your emphasis is on "group", the modern periodic table groups elements by similar electronic structure, and similar chemical behaviour.
Aside from the general fact that it would be much less useful in predicting chemical reactivity, some pairs of elements would be reversed from their current order. The most egregious reversal would be that of argon and potassium.
how would the modern periodic table be different if elements were arranged by average Atomic Mass instead of by atomic number
It would be different because a few elements would seem out of place in its group or periods.
Ni would come before Co. Bi and Po would come in the same place. Bi and Po would come before At.
Most of the elements would not be in the same groups or periods that they are now.
atomic number
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.

The Periodic Table is.
Elements also possess isotopes. So their average atomic mass is rarely whole number.
The periodic table is a function of the atomic number.

Periodic Table of elements.
the elements in the modern periodic table are arrange in the increasing order of their atomic numbers.
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.
The answer to, ' when repeating chemical and physical properties of elements change periodically with the elements' atomic numbers it is called the?'Periodic law, is the answer. PERIODIC LAW !orPeriodicity of the chemical elements properties.
On the right side of the periodic table.
