Explanation:

Step1: Recall atomic number facts

The atomic number is equal to the number of protons and in a neutral atom, the number of electrons.

Step2: Recall atomic mass formula

Atomic mass ≈ number of protons + number of neutrons. We can find neutrons as neutrons = atomic mass (rounded) - number of protons.

Oxygen (O)

• Atomic number = 8. So, # of protons = 8, # of electrons = 8. Atomic mass ≈ 16. # of neutrons = 16 - 8=8.

Zinc (Zn)

• Atomic number = 30. So, # of protons = 30, # of electrons = 30. Atomic mass ≈ 65. # of neutrons = 65 - 30 = 35.

Lithium (Li)

• Atomic number = 3. So, # of protons = 3, # of electrons = 3. Atomic mass ≈ 7. # of neutrons = 7 - 3 = 4.

Boron (B)

• Atomic number = 5. So, # of protons = 5, # of electrons = 5. Atomic mass ≈ 11. # of neutrons = 11 - 5 = 6.

Bromine (Br)

• Atomic number = 35. So, # of protons = 35, # of electrons = 35. Atomic mass ≈ 80. # of neutrons = 80 - 35 = 45.

Sulfur (S)

• Atomic number = 16. So, # of protons = 16, # of electrons = 16. Atomic mass ≈ 32. # of neutrons = 32 - 16 = 16.

Manganese (Mn)

• Atomic number = 25. So, # of protons = 25, # of electrons = 25. Atomic mass ≈ 55. # of neutrons = 55 - 25 = 30.

Magnesium (Mg)

• Atomic number = 12. So, # of protons = 12, # of electrons = 12. Atomic mass ≈ 24. # of neutrons = 24 - 12 = 12.

Argon (Ar)

• Atomic number = 18. So, # of protons = 18, # of electrons = 18. Atomic mass ≈ 40. # of neutrons = 40 - 18 = 22.
