Answer 1

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:

1. 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)
2. 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)
3. 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)
4. 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)
5. Fifth Row (Hydrogen Ion):
   • Number of Protons: Atomic number = 1
   • Number of Electrons: 0
   • Name of the Species: Protium Ion or Hydrogen Ion (H⁺)
