Using mass spectrometer, one can identify and/or separate the isotopes of the elements and also predict its composition in a given mixture.
By Atomic Mass
Mendeleev's version of the Periodic Table was organized by increasing mass. The modern periodic table is now organized by atomic number.
Mendeleev arranged the periodic table according to increasing atomic mass. This method has been used since he first developed it in the 1800s.
Look on a periodic table. If you have different isotopes then you need to multiply the mass number and atomic number and then find the average of them and you'll have the average atomic mass which is the same as on the periodic table. The location of the mass number on a periodic table depends but it's normally the one with a decimal.
You can "figure out" by checking the Periodic Table :D
No! The mass of one atom of each element increases as you move down and to the right on a periodic table. The mass of an atom of a particular element is called its atomic mass.
The atomic mass of phosphorus on the periodic table is approximately 30.974 grams per mole.
Beryllium has the lowest atomic mass in group 2 of the periodic table.
Atomic mass is determined by mass spectrometry.
