Root Explanation

The word 'isallobar' is derived from the Greek 'isos' (meaning equal) and 'allobar' (from 'allo-' meaning other and 'baros' meaning weight). It refers to a type of isotope that has the same mass number but different atomic numbers, thus being equal in mass but different in identity.

Memory Tip

Think of 'equal' ('isos') and 'other weight' ('allo-' and 'baros') to remember that an isallobar is an isotope that has the same mass but is different in atomic identity.
