The most stable isotope is rutherfordiun 267; for other isotopes see at: http://en.wikipedia.org/wiki/Rutherfordium
267
The atomic mass is the mass of a molecule, atomic particle or sub-atomic particle.
Cobalt is an atomic mass of 58.93 atomic mass units
== The equation of atomic mass is protons+nuetrons== atomic mass. ===
The atomic mass unit is not a SI unit. An atomic mass unit is equal to 1/12 from the atomic mass of the isotope 12C.
Atomic number 6, atomic mass 12.
The most stable isotopes of rutherfordium are: - atomic mass of 265Rf: 265,116 700 - atomic mass of 267Rf: 267,121 530 Masses after IUPAC recommendations, 2009.
261 amu. ------- The most stable isotopes of rutherfordium are: - atomic mass of 265Rf: 265,116 700 - atomic mass of 267Rf: 267,121 530 Masses after IUPAC recommendations, 2009.
The chemical symbol of rutherfordium is Rf.
Rutherfordium has an atomic symbol Rf and atomic number 104. Its atomic weight is 265. It is a metal that is silver or grey.
The atomic number of rutherfordium is 104.
Atomic mass of an element is measured in atomic mass units (amu), and is usually only slightly higher than its atomic mass number (except for elements having many different isotopes). The mass of a neutron is 1.00866 amu and the mass of a proton is 1.00728 amu. The mass of electrons is so insignificant that they are ignored. The atomic mass of an atom with 56 neutrons and 43 protons is (56 x 1.00866 amu) + (43 x 1.00728 amu) = ~99.8 amu.
The number of neutrons is different for each isotope. Number of neutrons = Atomic mass of an isotope - 104
