For instance, to a first approximation, 1 gram of hydrogen, which has a mass number of 1 (atomic number 1), has hydrogen atoms.
Similarly, 12 grams of carbon 12, with the mass number of 12 (atomic number 6), has the same number of carbon atoms,.
That is to say, after calculating EABF and EBF by using G-P fitting parameters of the elements with Z1 and Z2 atomic numbers for the energy in question, we have obtained EABF and EBF values of corresponding Zeff by interpolation.
Thus polonium-210 (mass number 210 and atomic number 84, i.e., a nucleus with 84 protons) decays by alpha emission to lead-206 (atomic number 82).
Element number 112 (its atomic number, which is the number of protons in its nucleus) was discovered by scientists at the Centre for Heavy Ion Research in Darmstadt, Germany.
To make the atoms of element 112, physicists fired zinc ions (atomic number 30) around a 120m particle accelerator at a lead target (atomic number 82), causing the nuclei of the atoms to fuse.
Over the years, these radiochemical techniques have been used to isolate and identify some 34 elements from zinc (atomic number 30) to gadolinium (atomic number 64) that are formed as fission products.
A bar of pure uranium, for instance, would consist entirely of atoms with atomic number 92.
In the final weeks, oxygen atoms fuse into silicon (atomic number 14), phosphorus (atomic number 15), and sulfur (atomic number 16).
Einsteinium-255 and einsteinium-256 eject electrons to form isotopes of fermium (atomic number 100), and mendelevium (atomic number 101) isotopes have been produced by bombarding einsteinium-253 "targets" with alpha particles in cyclotrons or linear accelerators.
The actinoid series consists of 15 elements from actinium (symbol Ac, atomic number 89) to lawrencium (symbol Lr, atomic number 103).
