Elements are organized in the Elements are organized in the periodic tableperiodic table by increasing by increasing atomic number.atomic number.

In the late 1800’s, Dmitri In the late 1800’s, Dmitri Mendeleev devised the first Mendeleev devised the first periodic table based on periodic table based on atomic atomic massmass..

In 1913, Henry G. J. Moseley In 1913, Henry G. J. Moseley arranged the elements by arranged the elements by atomic atomic numbernumber rather than atomic mass. rather than atomic mass.

Atomic Number = # of protons and electrons (except for isotopes)

Atomic Mass = measurement of the total number of particles in the nucleus.

Round the atomic mass to find the mass number. Then subtract the atomic number to find the number of neutrons.

Number of Protons = 36

Number of Electrons = 36

Number of Neutrons = 48
