| ELEMENT ATOMIC MASS (ISOTOPE) UNITS ( OF AN ELEMENT) EXISTS IN A PAIRED CONFIGURATION. Plus ONE ... creating odd quantity ISOTOPE progression ... thru each element. This progression is predictable. If an abundance % has not been determined ... the table uses this progressive isotope amount as the atomic mass for that element. |
