Question

the nuclii having same number of nutrons but different mass numbers are called as​

Answer 1

Answer:

Atoms of the same element that differ in their numbers of neutrons are called isotopes. Many isotopes occur naturally. Usually one or two isotopes of an element are the most stable and common. Different isotopes of an element generally have the same physical and chemical properties.

Answer 2

Explanation:

The nuclei having same number of neutrons but different mass numbers are called as isotones

For example : ²³⁴Ra ( atomic number 88 ), ²³⁵Ac ( atomic number 89), ²³⁷Pa ( atomic number 91) and ²³⁸U ( atomic number 92), since each has 146 neutrons .
