Chemisty Packing Fraction

Nidhi T.

Explain packing fraction.

Packing fraction is defined as a way of expressing the variation of isotopic mass from whole mass number (atomic mass).


Packing fraction

This fraction can have positive or can have negative sign.

A positive packing fraction describes a tendency towards instability.

A negative packing fraction means isotopic mass is less than actual mass number. This difference is due to the transformation of mass into energy in the formation of nucleus.
