To find the number of neutrons and protons in the given nuclei, we can use the following formulas: 1. The atomic number (Z) represents the number of protons in the nucleus. 2. The mass number (A) represents the total number of protons and neutrons in the nucleus. 3. The number of neutrons can be calculated using the formula: \[ \text{Number of Neutrons} = A - Z \] Now, let's solve the problem step by step for each nucleus. ...
