Explanation:

Step1: Recall atomic number and basic facts

Atomic number = number of protons = number of electrons in a neutral atom. We use the periodic - table to find neutrons (neutrons = mass number - atomic number, for common isotopes we use well - known values). Also, group and period can be found from the periodic table.

Step2: For Sodium (Na)

Atomic number of Na is 11. So, number of protons = 11, number of electrons = 11. Common isotope of Na has mass number 23, so number of neutrons = 23 - 11=12. Total number of particles = 11 + 11+12 = 34. It is in group 1 and period 3.

Step3: For Magnesium (Mg)

Atomic number of Mg is 12. Given number of protons = 12, number of electrons = 12. Common isotope of Mg has mass number 24, so number of neutrons = 24 - 12 = 12. Total number of particles = 12+12 + 12=36. It is in group 2 and period 3.

Step4: For Aluminum (Al)

Atomic number of Al is 13. Given number of protons = 13, number of electrons = 13. Common isotope of Al has mass number 27, so number of neutrons = 27 - 13 = 14. Total number of particles = 13+13 + 14=40. It is in group 13 and period 3.

Step5: For Phosphorus (P)

Atomic number of P is 15. Given number of protons = 15, number of electrons = 15. Common isotope of P has mass number 31, so number of neutrons = 31 - 15 = 16. Total number of particles = 15+15 + 16=46. It is in group 15 and period 3.

Step6: For Silicon (Si)

Atomic number of Si is 14. Given number of protons = 14, number of electrons = 14. Common isotope of Si has mass number 28, so number of neutrons = 28 - 14 = 14. Total number of particles = 14+14 + 14=42. It is in group 14 and period 3.

Step7: For Sulfur (S)

Atomic number of S is 16. Given number of protons = 16, number of electrons = 16. Common isotope of S has mass number 32, so number of neutrons = 32 - 16 = 16. Total number of particles = 16+16 + 16=48. It is in group 16 and period 3.
