Solution
| Mass number | Mass number | Number of Neutrons | Number of protons | Number of electrons | Name of the Atomic species |
| 9 | 19 | 10 | 9 | 9 | Fluorine |
| 16 | 32 | 16 | 16 | 16 | Sulphur |
| 12 | 24 | 12 | 12 | 12 | Magnesium |
| 1 | 2 | 1 | 1 | 1 | Deuterium |
| 1 | 1 | 0 | 1 | 0 | Hydrogen ion |
Explanation:
- First Row (Fluorine):
- Mass Number: 19 = Atomic number (9) + Number of neutrons (10)
- Number of Protons: Atomic number = 9
- Number of Electrons: Atomic number = 9
- Name of the Species: Fluorine (F)
- Second Row (Sulphur):
- Number of Neutrons: 32 - Atomic number (16) = 16
- Number of Protons: Atomic number = 16
- Number of Electrons: Atomic number = 16
- Name of the Species: Sulphur (S)
- Third Row (Magnesium):
- Number of Protons: Atomic number = 12
- Number of Neutrons: 24 - Atomic number (12) = 12
- Number of Electrons: Atomic number = 12
- Name of the Species: Magnesium (Mg)
- Fourth Row (Deuterium):
- Number of Protons: Atomic number = 1
- Number of Neutrons: 2 - Atomic number (1) = 1
- Number of Electrons: Atomic number = 1
- Name of the Species: Deuterium (D)
- Fifth Row (Hydrogen Ion):
- Number of Protons: Atomic number = 1
- Number of Electrons: 0
- Name of the Species: Protium Ion or Hydrogen Ion (H⁺)
