select the point of isotones from the following nuclei `""._(12)Mg^(24),""._(1)H^(3),""._(2)He^(4),""._(11)Na^(23)`.

Explanation

To determine the isotones from the given nuclei, we need to calculate the number of neutrons in each nucleus. The number of neutrons can be found using the formula:

\[ \text{Number of Neutrons} = A - Z \]

where \( A \) is the mass number and \( Z \) is the atomic number.

Let's analyze each nucleus step by step:
