How would the modern periodic table would be different if elements were arranged by average atomic mass instead of by atomic number?
how would the modern Periodic Table be different if elements were arranged by average Atomic Mass instead of by atomic number
What else can I help you with?
By what property did Mendeleev suggest that the periodic table be arranged?
Madeleev originally arranged the elements in the first periodic table by their average atomic masses. Later it was changed to atomic number by Moseley, or the number of protons each of that element's atom has.
What does the periodic table contain?
The four pieces of information in each box of most periodic tables are the element's name, the element's symbol, the element's average atomic weight and the element's atomic number. Other periodic tables have other information, but standard periodic tables almost always have those four.
How did mendeleev first worked out this order of elements?
Dmitri Mendeleev arranged the elements by increasing atomic mass and similar chemical properties. He left gaps for undiscovered elements and predicted their properties based on the pattern he observed, leading to the development of the periodic table.
What is the contribution of Dobereiner to the periodic table?
He provided the base for the classification of elements he says the elements are atomic masses nearly same he arranged the atomic masses of the middle element is approximately the arithmetic mean of other two elements,He first gave us the ''Law of Triads''...where he made lists of three elements each, and showed that the mass of the middle element is approximately equal to the average mass of the other two elements.
What is average atomic number?
There is no average atomic number. The atomic number of an element is the number of protons in the nuclei of its atoms. It is a whole and finite number. The elements are arranged in order of increasing atomic number on the periodic table.

What scientist published the first periodic table and how was it arranged?
In 1817, Döbereiner began to formulate one of the earliest attempts to classify the elements. He found that some elements formed groups of three with related properties. He termed these groups "triads". In all of the triads, the atomic weight of the second element was almost exactly the average of the atomic weights of the first and third element..
Are elements in the periodic table organized by their atomic numbers or their average masses?
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
How do you calculate average atomic number of an element?
There is no average atomic number. The atomic number of an element is the number of protons in the nuclei of its atoms. It is a whole and finite number. The elements are arranged in order of increasing atomic number on the periodic table.

Do the elements in a row on the periodic table have the same average atomic mass?
no.
How are the atomic numbers and the atomic masses of the elements related to how the elements are arranged on peridoic table?
Elements are arranged in a periodic table by atomic number, lower on top and left. Atomic masses have no direct relationship to the arrangement of atoms, although generally atoms with higher atomic numbers will have higher atomic masses. (There are at least three exceptions for atoms with atomic numbers differing by 1.)
The first periodic table was arranged by?
Demitri Mendeleev. He arranged it by atomic mass
Why elements don't have whole numbers?
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

Why is atomic mass for an element an average on the periodic table?
The atomic mass is an average because most atoms have isotopes sometimes up to 10 or more. These all have different numbers of neutrons and subsiquently different weights. For this reason an average of these weights needs to be used for the atomic mass.
