- 6. property of having poles or being polar.
- 7. of two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei, and hence differ in relative atomic mass but not in chemical propertiesLawofconservationofmass the principle that in any closed system subjected to no external forces, the mass is constant irrespective of its changesNeutron
- 10. assets in excess of liabilities; able to pay one's debts.
