Question

Thank you for your help on this. 

**Exercise: Complete the following table** | Species | Protons | Electrons | Neutrons | Charge | |---------|---------|-----------|----------|--------| | \( ^{41}\text{Ca} \) | 20 | 20 | 21 | 0 | | | 25 | 25 | 30 | 0 | | | 47 | 47 | 62 | 0 | | | 17 | 18 | 20 | 1- | | \( ^{24}\text{Mg}^{2+} \) | 12 | 10 | 12 | 2+ | Detailed Instructions: 1. For each species listed, determine and fill in the number of protons, electrons, and neutrons. 2. Use the atomic number to find the number of protons. 3. The charge will help determine the number of electrons. 4. The mass number minus the atomic number will give the number of neutrons. **Example solved (first row for species \( ^{41}\text{Ca} \))**: - Atomic number of Calcium (\( \text{Ca} \)) is 20, therefore, it has 20 protons. - Mass number is given as 41, so the number of neutrons is \( 41 - 20 = 21 \). - Charge is neutral (0), so the number of electrons is equal to the number of protons, which is 20.
