Two nuclides A and B are isotonic .Their mass number are `76` and `77` respectively .If the atomic number of A is 32 then the atomic number of B will be

Options

A. `33`
B. `34`
C. `32`
D. `30`

Explanation

To find the atomic number of nuclide B, we can follow these steps:

### Step 1: Understand the concept of isotonic nuclides
Isotonic nuclides are nuclides that have the same number of neutrons but different mass numbers and atomic numbers. This means that the difference between the mass number and the atomic number for both nuclides will be the same.

### Step 2: Identify the given information
- Mass number of nuclide A (m1) = 76
- Atomic number of nuclide A (z1) = 32
