relative atomic mass betydelse and definition

Exempel på relative atomic mass

• For the natural isotopic composition of each element it shows "name", "atomic number", "symbol", "atomic weight" (or relative atomic mass) and a link to the element's "isotopes".

• It is numerically equal to the relative atomic mass (or atomic weight) in grams.

• However, atomic weight, ie, relative atomic mass, is a dimensionless quantity, and can not take the units of grams per mole.

• Si, which has a relative atomic mass of.

• Its isotopic composition would be measured with a mass spectrometer to determine its average relative atomic mass.

• The term "atomic weight" is being phased out slowly and being replaced by "relative atomic mass", in most current usage.

• The relative atomic mass (a weighted average) of these isotopes is the atomic weight listed for the element in the periodic table.

• It is fixed by the definitions of the mole and of relative atomic mass.
