A) isotopes
B) isobars
C) isotones
D) isodiaphers
Correct Answer: C
Solution :
Isotones : Nuclei having different atomic number and different mass number but having same number of neutrons are known as isotones e.g., In \[{{\,}_{\text{19}}}{{\text{K}}^{\text{39}}}\]number of neutrons = 39 -19 = 20 In \[{{\,}_{20}}\text{C}{{\text{a}}^{40}}\] number of neutrons = 40 - 20 = 20 Both have same number of neutrons. So, these are isotones.You need to login to perform this action.
