Each element on the Periodic Table has two numbers: the atomic number and the relative Atomic Mass. The atomic number is the number of protons in the nucleus, and the relative atomic mass is the total number of protons and neutrons (so the difference between them is the number of neutrons). The relative atomic mass is always the higher of the two.

What element has an atomic mass of 50.9?
Vanadium has an atomic weight of 50.9415 on the periodic table.
The atomic mass is determined by?
atomic mass is determined by adding the number of protons and neutrons.this can be seen in the periodic table as the average atomic mass below the name of the element
What is the formula for atomic mass of carbon?
You don't need a formula for that. It's on the periodic table.
What is the formula for mass of solid?
nM=m moles of solid multiplied by Molar mass (Atomic mass on periodic table) = Mass of solid
How were the elements in the periodic table arranged?
By Atomic Mass
How are atomic mass on the periodic table calculated?
Atomic mass is determined by mass spectrometry.
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 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
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.
What atomic mass is equal to the atom on the periodic table?
number of protons = atomic mass
In what order did Mendeleev arrange the elements in the first periodic table?
Mendeleev arranged the elements in the periodic table according to their atomic masses.
Use the periodic table to find the atomic mass of phosphorous?
The atomic mass of phosphorus on the periodic table is approximately 30.974 grams per mole.
Which element has lowest atomic mass in group 2 on periodic table?
Beryllium has the lowest atomic mass in group 2 of the periodic table.
