Question

The nuclides haveing mass no between 30 to 90 are called​

Answer 1

Answer:

This list of nuclides shows observed nuclides that either are stable or, if radioactive, have half-lives longer than one hour. This represents isotopes of the first 105 elements, except for elements 87 (francium) and 102 (nobelium). At least 3,300 nuclides have been experimentally characterized[1] (see List of radioactive nuclides by half-life for the nuclides with decay half-lives less than one hour).

A nuclide is defined conventionally as an experimentally examined bound collection of protons and neutrons that either is stable or has an observed decay mode.
