Explanation:

Situation 1

The mass number = 35 = The sum of the protons and the neutrons in an atom

The number of protons = 17

The net charge = 1

3. The atomic  number = The number of proton = 17

4. The number of neutrons = Mass number – Atomic number

∴ The number of neutrons = 35 – 17 = 18

5. Given that the net charge of the atom = +1, the number of electrons in the atom is 1 less than the number of protons

Therefore, the number of electrons = 11 – 1 = 10

6. Positively charged ions are called a cation

The atom is a positively charged and it is therefore it is a cation

Situation 2

The number of protons =  35

The number of neutrons = 46

The net charge = -1

7. The atomic number = The number of protons = 35

8. The mass number = The number of protons + The number of neutrons

∴ The mass number = 35 + 46 = 81

9. The number of electrons = The number of protons + 1

∴ The number of electrons = 35 + 1 = 36

10. The type of atom is an anion

Situation 3

Atomic number = 37

Mass number = 85

Number of electrons = 36

11. The number of protons = The atomic number = 37

12. The number of neutrons = The mass number – The atomic number

∴ The number of neutrons = 85 – 37 = 48

13. The net charge = The atomic number – The number of electrons

∴ The net charge = 37 – 36 = +1

14. Given that the net charge = +1, the type of atom is a cation

Situation 4

Mass number = 11

Number of neutrons = 6

Net charge = +3

15. The atomic number = The mass number – The number of neutrons

∴ The atomic number = 11 – 6 = 5

16. The number of protons = The atomic number = 5

17. Given that the net charge is +3, we have;

The number of electrons = The number of protons – The net charge

∴ The number of electrons = 5 – (+3) = 2

18. The type of atom with a net positive charge (+3) is a cation
