The atomic mass of ruthenium is 101.07
The element that is placed in the same period as ruthenium (which is in period 5) but has a higher atomic number is silver (Ag), with an atomic number of 47. Ruthenium has an atomic number of 44. Both elements are transition metals found in the d-block of the periodic table.
The atomic weight of ruthenium to 3 digits after the dot is 101.065 unified atomic mass units. The formula for calculating atomic weight is: n ∑(wx*px) x=1 where: n is the number of isotopes you have the data for. w is the weights of the isotopes. p is the percent compositions of the isotopes in decimal form. ∑ is the summation symbol.

Atomic mass
The atomic mass (or weight) of silver is 107.8682 amu (atomic mass units)
The atomic mass number of aluminum is 27. The atomic mass of aluminum is 26.98115386
The atomic number of ruthenium (Ru) is 44.The atomic weight of Ru is 101.07 grams per mole.See the Web Links to the left of this answer for a periodic table with more information about this element!
Ruthenium has 44 protons since the atomic number represents the number of protons in an atom. Since the mass number is 101, it implies the sum of protons and neutrons in the nucleus is 101, so the number of neutrons in this case would be 101 - 44 = 57.
The closest to 44 is Scandium, which has 21 protons and 24 neutrons, giving it a mass of 44.95591 amu.
