Question

which of the following pair is isodiaphers (a) C-14 and Na-23 (b) Mg-24 and Na-23 (c) He-4 and O-16 (d) C-12 and N-
15​

Answer 1

Answer:

(d) c -12 and n- 15

( d) C-12 and N-15

Answer 2

Answer:

From the given options, the correct option is (d) C-12 and N-15​.

Explanation:

• Isodiaphere are nuclides that have the same number of protons and neutrons in their nucleus.
• Despite the fact that the nuclei of both nuclides have different numbers of protons and neutrons, the difference is the same.
• In simpler terms, two atoms are isodiaphere when the difference between their Mass Number 'A' and Atomic Number 'Z' is equal.
• The same is true for the U238 atom. Because their nuclide excesses are identical, we can conclude that these two atoms are isodiaphere.
• Isodiaphere are nuclides that have the same number of protons and neutrons in their nucleus.
• For example: the difference between uranium 23892U and thorium 90234Th is 54.
