Atomic Mass of First 30 Elements - Atomic Mass of Elements is Measured with the Help of its Unit - Atomic Mass Unit. One such Unit is Equal to One-Twelfth of the Mass of a Carbon-12 Atom Which is at Rest. Learn about Atomic Mass of First 30 Elements at B
Holmium occurs with other rare earth elements in minerals such as monazite and gadolinite. It can now be separated from other rare earth elements somewhat easily. But no major uses have been found for it or its compounds. SYMBOL Ho ATOMIC NUMBER 67 ATOMIC MASS 164.9303 FAMILY ...
The transactinides are elements with atomic numbers Z≥104. They are all man-made elements synthesized at accelerators using nuclear reactions of heavy-ion beams with heavy element target materials and they can only be identified by measuring their characteristic nuclear decay or that of their known...

For example, the atomic mass of chlorine (Cl) is 35.45 because chlorine is composed of several isotopes, some (the majority) with atomic mass 35 (17 protons and 18 neutrons) and some with atomic mass 37 (17 protons and 20 neutrons)....
Julesium is a hypothetical Yoso element with the atomic number y330 and the symbol Jul. It is named after Gary Jules. Julesium is possibly a colourless solid at room temperature. Julesium is radioactive and has no stable isotopes. Its most stable isotope
Thus the atomic mass of oxygen is expressed as the weighed average of the atomic masses of these three isotopes. Atomic mass of oxygen=[(99.763*15.995)+(0.037*16.999)+(0.2*17.999)]/100 = 15 u
According to the density deficit between pure Fe and PREM (~10% at outer core and 3.6% at inner core boundary)47,48,49, the doping proportion of elements with heavier relative atomic mass than Fe (heavy-elements) should be low, so that high density should be compensated without the need...
