Elasticity equals stress divided by strain . Mass of element remains constant, but atomic number decreases by 1. Fundamental properties of an element are determined by number of protons, each element assigned a number corresponding to its number of protons. Combinations containing from 1 through 103 protons are now known. Sometimes called terminal moraine .
Energy holds matter together and can become mass or be derived from mass.
