Atomic Mass is determined by mass spectrometry.

How were the elements in the periodic table arranged?
By Atomic Mass
Mass number Why is it not the number on the periodic table?
Elements have different isotopes and each isotope will have different atomic mass. As such it is not possible to list the mass number of all the isotopes on the periodic table. However, the atomic mass is generally given on the periodic table which is generally calculated taking into account all the isotopes and its percentage.
What characteristic was used to organize the first periodic table?
Mendeleev arranged the periodic table according to increasing atomic mass. This method has been used since he first developed it in the 1800s.
How is the current periodic table of the elements organized?
Mendeleev's version of the Periodic Table was organized by increasing mass. The modern periodic table is now organized by atomic number.
What does the atomic number and atomic mass have to do with the arrangement of the elements on the periodic table?
The elements on the periodic table are arranged in order of increasing atomic number.
How is the relative atomic mass calculated for elements on the periodic table?
The relative atomic mass of an element is calculated by taking the weighted average of the masses of its isotopes, based on their abundance in nature. This value is listed on the periodic table below the element's symbol.

How do you find the atomic mass and the atomic number?
The atomic number is the whole # on the periodic table or the # of protons in an atom. The atomic mass is the # that is not the whole # on the periodic table, or you can multiply the mass of the isotope by its abundance and add the answers together.
How do you find the mass number on the periodic table for the elements are calculated?
The mass number is the number of protons plus the number of neutrons in the atomic nucleus.
How is the current periodic table of the elements organized?
Mendeleev's version of the Periodic Table was organized by increasing mass. The modern periodic table is now organized by atomic number.
Is your modern periodic table based on atomic mass or atomic number?
The modern periodic table is arranged according to the elements' atomic numbers.
What does the atomic number and atomic mass have to do with the arrangement of the elements on the periodic table?
The elements on the periodic table are arranged in order of increasing atomic number.
What is the benefit of organizing the periodic table in columns?
the benefit is that you can tell the atomic number atomic mass its symbol and where it is on the periodic table
What atomic mass is equal to the atom on the periodic table?
number of protons = atomic mass
Who organized the periodic table by atomic number?
Arranging the Periodic Table by atomic number rather than Atomic Mass was first suggested by a British man named Henry Moseley in 1913. Before that point, the periodic table was organized by atomic mass, and has several inconsistencies and problems.
